This week on Womanity, Dr Amaleya Goneos-Malka speaks with Professor Mercy Kazima, Professor of Mathematics Education at the University of Malawi. From a lifelong fascination with mathematical logic to a career devoted to helping others experience the breakthrough of “now I understand”, Professor Kazima’s journey shows how education can build confidence, widen opportunity and contribute to national development. Her story brings together teaching, research, leadership and a determined commitment to ensuring that girls and women can claim their place in mathematics, science and academia. She has led major international research projects, served as President of the Southern Africa Association for Research in Mathematics, Science and Technology Education, and is a passionate advocate for girls’ participation in mathematics and science Refusing the Ceiling on Women’s Ambition As a girl and young woman, Professor Kazima repeatedly encountered the message that mathematics was too difficult for girls and that she had already achieved “enough”. Instead of accepting those expectations, she chose to pursue an honours degree and deepen her mathematical expertise. Her experience reveals that the most powerful barriers are not always ability or talent, but the social ceilings placed on women’s aspirations. Believe in Your Potential Before Others See It A central lesson in her story is the importance of defining your own dream. Professor Kazima urges girls to listen thoughtfully to advice without allowing other people’s fears or limitations to become their own. Perseverance, self-belief and clarity of purpose enabled her to continue when others questioned her choices, and remain the qualities she recommends to anyone pursuing an ambition that challenges convention. When the First Woman Opens the Door In 2009, Professor Kazima became the first woman Dean of the Faculty of Education at the University of Malawi since the university’s establishment in 1965. She describes the appointment as both a proud personal achievement and a significant public responsibility. Knowing that women and girls were watching, she wanted her leadership to make visible what had previously seemed impossible: that a woman could occupy the role, excel in it and expand the ambitions of those coming behind her. Representation Must Become Opportunity Visibility matters, but Professor Kazima cautions that representation alone does not automatically advance other women. Women in leadership must actively support growth, create opportunities and keep doors open, while women around them should also support those who step forward. Her international experience reinforced the power of seeing women lead, and the responsibility to turn individual success into collective progress. Research That Changes Real Classrooms Professor Kazima’s research moves beyond theory into the realities of multilingual classrooms, early numeracy and mathematics teacher education. One of her strongest findings is that lasting improvement cannot come from simply telling an individual teacher to teach better. Teachers need strong subject knowledge, sound pedagogy, appropriate resources and structured opportunities to observe one another, reflect together and develop as a professional community. Equality Means More Than Getting Girls Through the School Gate The conversation explores the many layers of educational inequality, including differences in resources, qualified teachers and learning opportunities between rural and urban schools. Professor Kazima argues that access is only the beginning. Genuine equality means asking whether girls are participating, building confidence, progressing, remaining in school and discovering what their education can enable them to become. Making Mathematics a Space for Everyone During eight years coordinating the Malawi National Mathematics Olympiad, Professor Kazima saw how powerful it was for schoolgirls to encounter a woman leading in a field still widely associated with boys. Bringing finalists onto a university campus helped young participants imagine a future beyond the competition itself. Her presence delivered a message as important as any mathematical solution: girls belong in this space and can lead within it. Leadership Built on Purpose, Discipline and Integrity Professor Kazima identifies discipline, persistence, resilience and a strong sense of purpose as the foundations of her success. For her, leadership also requires continuous learning, listening to disagreement, building shared vision and understanding the policies that govern an institution. Integrity means living by those standards, setting an example and using leadership not simply to advance oneself, but to help others grow. A Message to Women and Girls Professor Kazima closes with a challenge: do not let other people’s limitations define your dreams. Girls should identify what they want, believe in their potential and work to reveal it. Women should not be afraid to take up positions of responsibility, and when they succeed, they should inspire others, create room for them to grow and never close the door behind them.

This week on Womanity, Dr Amaleya Goneos-Malka speaks with Dr Malini Bhana, a specialist general surgeon focused on hepatopancreatobiliary (HPB) surgery, one of medicine’s most intricate and demanding fields. From an early interest in research to discovering the practical, problem-solving power of surgery, Dr Bhana’s journey reflects curiosity, discipline and a commitment to helping patients through some of the most vulnerable moments of their lives. Finding Her Place in the Operating Theatre Initially drawn to the academic and research side of medicine, Dr Bhana could not imagine herself in clinical work. That changed during internship. Despite warnings that surgery would be gruelling, she found a field that matched the way she thinks: assess the problem, plan a solution, act decisively and help the patient recover. The hands-on nature of the work made everything fall into place. The Precision and Challenge of HPB Surgery After being captivated by the speed and adrenaline of trauma surgery, Dr Bhana was drawn to the deeper planning and technical precision of HPB procedures involving the liver, pancreas, gallbladder and bile ducts. These complex operations demand detailed anatomical knowledge, meticulous preparation and sustained concentration. For her, that difficulty is precisely part of the appeal. A Defining Whipple Procedure One patient remains unforgettable: the first person on whom Dr Bhana performed a Whipple procedure independently during her fellowship. The six-to-eight-hour operation for pancreatic cancer involves removing several structures and performing a complex reconstruction. Guiding that patient from diagnosis through surgery, recovery and discharge marked the moment she felt she had achieved a long-held professional goal. Laser Focus, Stamina and Humanity Long operations require both physical fitness and an extraordinary ability to focus. Dr Bhana explains that when a life is in her hands, the patient on the table becomes the only priority. Yet she does not see emotional investment as a weakness. Caring deeply must be balanced with clear decision-making, perspective, trusted colleagues, opportunities to debrief and a life beyond medicine. Women’s Health: Symptoms That Should Not Be Dismissed The conversation offers an important health message for women. Dr Bhana discusses women’s greater susceptibility to gallstones and certain liver adenomas, and cautions against dismissing persistent upper or right-sided abdominal pain, nausea or vomiting. Her message is simple: listen to your body, seek medical advice and do not ignore symptoms that continue. Rethinking a Profession Built Around Extreme Hours Although more women are entering surgery, Dr Bhana is candid about the structural obstacles that remain. Training, on-call duties and unpredictable operations do not fit neatly around family responsibilities, while extreme fatigue can become unsafe for clinicians and patients alike. Flexible programmes are emerging, but the challenge is to create sustainable pathways without depriving trainees of essential experience. Representation Changes What Women Believe Is Possible For Dr Bhana, gender equality is about more than equal numbers. It means a workplace where gender does not limit opportunity or diminish the value placed on someone’s contribution. Seeing women perform complex surgery, lead professional bodies and speak on international platforms can expand other women’s sense of what is possible. Opportunity should be open to all, with achievement grounded in skill and merit. Mentorship Opens Doors Mentors played a decisive part in Dr Bhana becoming an HPB surgeon. To her, mentorship goes far beyond teaching technique: it is having someone who believes in you, helps you navigate difficult decisions and encourages you to pursue opportunities you may not recognise in yourself. Her involvement in teaching, the European-African Hepato-Pancreato-Biliary Association and the HPB Insights podcast allows her to pass that support forward while connecting with a wider international community. Bringing Specialist Care Closer to Home Establishing her own practice at Mediclinic Limpopo has given Dr Bhana the opportunity to shape care around meticulous preparation, continuity and individual attention rather than volume. It also brings scarce specialist services closer to patients who previously had to travel to Johannesburg or Pretoria, allowing them to remain nearer to the families and support networks that matter during treatment. Define Success for Yourself Dr Bhana credits a supportive family, inspiring women, hard work and the freedom to follow what she loves. Her closing message to girls and young women is to take opportunities, resist other people’s limitations and define success on their own terms. A meaningful life can hold ambition and personal fulfilment together and when no one like you is visible in the room, sometimes the task is to become the first and open the door for those who follow.

This week on Womanity, Dr Amaleya Goneos-Malka speaks with neurosurgeon Dr Lauren Ford, whose work spans traumatic brain injury, neurosurgical oncology and spinal surgery. From a childhood fascination with medicine to a career operating at millimetre-level precision, Dr Ford shares the experiences, relationships and determination that shaped her path. The conversation moves beyond the operating theatre to explore women’s neurological health, compassionate patient care, the realities of a demanding surgical career and the importance of perseverance. When the Speciality Chooses You Dr Ford says she always wanted to be a doctor. Early encounters with serious illness; her own childhood medical emergency and her younger brother’s recovery from multi-organ failure and a stroke, gave that ambition a deeply personal foundation. Her fascination with the brain and nervous system began early, and by Grade 9 she was already imagining the seemingly impossible. In her words, neurosurgery ultimately “chose” her. Where Millimetres Matter Neurosurgery demands extraordinary accuracy: a deviation of one or two millimetres can have catastrophic consequences. Dr Ford explains how magnifying loupes, microscopes, careful positioning and steady hands support delicate brain procedures, while spinal surgery calls for a different kind of physical endurance. Across both, technical excellence must be matched by calm judgement and an acute awareness of what is at stake. “Time Is Brain” Working in high-volume public hospitals exposed Dr Ford to severe trauma and unforgettable emergencies, such as men walking into casualty with bottles in their heads or knives in their necks. She describes the urgency of treating brain bleeds, where every delay can worsen the outcome, and recalls an 89-year-old patient who survived after an emergency procedure and still returns to visit her. These cases capture the intensity of the field, and the profound reward of seeing a patient walk out of hospital when there was once very little hope. Patients Are Never Just Numbers For Dr Ford, medicine is as much about connection as intervention. She speaks movingly about a young patient whom she operated on three times, making sure the child, not only her parents, understood what was happening. Their continuing bond reflects her belief that good care means walking a path with patients and families, including through the uncertainty and grief that can accompany brain tumours. A Female Lens on Neurological Health The interview highlights neurological conditions that may affect women differently or more frequently, including meningiomas, aneurysms, carpal tunnel syndrome, prolactinomas and benign intracranial hypertension. Dr Ford encourages women to pay attention to new or unexplained symptoms such as changes in smell or vision and severe pressure headaches, while stressing that symptoms and treatment depend on the individual and the location of the condition. Women in a Demanding Surgical World Neurosurgery is becoming more inclusive, but its long hours and relentless demands still create particular pressures for women balancing professional and family responsibilities. Dr Ford reflects on entering a field with very few female specialists and seeing more women now qualify each year. She also argues that women bring valuable dimensions to medicine, including empathy, communication and a willingness to sit with patients through difficult moments. Success Is Built on Support Behind Dr Ford’s achievements is a strong network: a supportive partner, a close-knit family, faith, mentors and accomplished women who model purposeful lives. She protects her own balance through exercise, singing in a community choir and making room for interests beyond medicine. Her experience in private practice has also required her to learn new skill sets of leadership, finance and business management, without losing the compassionate heart of a doctor. A Message to the Next Generation The conversation closes with a simple, powerful message: do not give up. Dr Ford was not accepted into medicine in the first round, but she kept applying, kept working and stayed true to the career she wanted. For girls considering science, medicine or surgery, her advice is to choose subjects carefully, pursue excellence, seek practical exposure and work hard. Passion may open the door, but perseverance carries you through it. Tune in for more…

Dr Lauren Ford – Neurosurgeon – Solutionist

This week on Womanity, Dr Amaleya Goneos-Malka speaks with neurosurgeon Dr Lauren Ford, whose work spans traumatic brain injury, neurosurgical oncology and spinal surgery. From a childhood fascination with medicine to ...

This week on Womanity, Dr Amaleya Goneos-Malka speaks with Professor Sophie Von Der Heyden from the Department of Botany and Zoology at Stellenbosch University and the Von Der Heyden Laboratory. She is a leading marine molecular ecologist, renowned for her pioneering work in aquatic biodiversity, conservation genomics, and climate change research. From East Berlin to the Oceans of Africa Professor von der Heyden’s story begins far from the shores and aquatic ecosystems that would eventually define her career. Growing up in East Berlin, she credits her early fascination with nature to family influences, particularly her brother, who introduced her to exploring and observing wildlife. She reflects on the freedom she experienced as a child; freedom to explore, question, and discover, which she believes laid the foundations for her curiosity-driven approach to science. Why Aquatic Ecosystems Matter Professor von der Heyden explains why aquatic ecosystems continue to captivate her. Oceans, rivers, estuaries, and wetlands remain among the least understood environments on Earth, despite their immense importance to biodiversity, climate regulation, and human livelihoods. She describes Africa as a continent rich with scientific opportunity because so much remains undiscovered. While limited funding and research capacity present challenges, they also create extraordinary opportunities for innovation and discovery. Her work is driven by a desire to contribute pieces to the larger scientific puzzle that ultimately supports better conservation, management, and restoration of vulnerable ecosystems. Building Knowledge Through the Von der Heyden Lab As founder and leader of the Von der Heyden Lab, Professor von der Heyden is passionate about developing the next generation of scientists. While groundbreaking discoveries are important, she emphasises that one of her most significant contributions has been building scientific capacity in Africa. Her laboratory has helped introduce and advance molecular ecology and genomic techniques across the continent, enabling African researchers to address environmental challenges using cutting-edge scientific tools. Through mentorship, teaching, and collaboration, she seeks to create opportunities for emerging scientists while strengthening Africa’s ability to conduct world-class biodiversity research. Climate Change Beneath the Surface While climate change is often discussed in terms of weather events, agriculture, and rising temperatures on land, Professor von der Heyden highlights the profound effects occurring beneath the water's surface. She explains how rising ocean temperatures, ocean acidification, sea-level rise, and changing environmental conditions are affecting marine and freshwater species. Many organisms are being forced to shift their geographical ranges in search of suitable habitats, while others, particularly species restricted to estuaries or isolated ecosystems, have nowhere to go. The conversation also explores concepts such as "coastal squeeze," where natural habitats like salt marshes and seagrass meadows become trapped between rising seas and human development. These combined pressures illustrate the complex and interconnected nature of environmental challenges. Finding Hope Through Action Despite the seriousness of climate change, Professor von der Heyden stresses the importance of focusing on solutions rather than despair. She encourages individuals to consider practical actions that reduce their environmental footprint, including: Reducing unnecessary travel Walking and using sustainable transport where possible Supporting locally produced food (food has travel miles too) Being conscious of consumption habits Reducing waste and packaging Understanding personal carbon footprints She shares a memorable teaching exercise where students compared their carbon footprints with those of their grandparents, often discovering that previous generations lived significantly more sustainable lifestyles despite having fewer resources. Her message is clear: meaningful change begins with informed, conscious choices Women in Science: Progress and Remaining Challenges Professor von der Heyden reflects positively on the growing participation of women in marine sciences and STEM fields. Over the course of her career, she has witnessed significant increases in female representation and leadership within scientific disciplines. However, she notes that important challenges remain, particularly around retaining talented women in research careers. Balancing professional ambitions with family responsibilities, caregiving, and personal wellbeing continues to be a reality for many women. She advocates for supportive environments, mentorship, and institutional cultures that enable women to flourish at different stages of their careers. Preparing Young People for an Uncertain Future The discussion also turns to education and the future of work. Professor von der Heyden argues that today's careers are far less linear than in previous generations. In a world increasingly shaped by technology and artificial intelligence, she believes the most valuable skills are: Critical thinking Problem-solving Numerical literacy Adaptability Communication and interpersonal skills While technical knowledge remains important, she suggests that the ability to evaluate information, think independently, and build meaningful human connections will become even more critical in the future. Balancing Science, Family and Life As a mother of three and a successful academic leader, Professor von der Heyden speaks candidly about the realities of balancing family life with a demanding career. She acknowledges the guilt and uncertainty she experienced as a young researcher and parent, but emphasises that balance evolves over time rather than being perfectly achieved. One of her pieces of advice is to accept help when it is offered. She credits much of her success and well-being to the community she has built around her; family, friends, colleagues, and mentors who have provided support throughout different stages of her life. Her perspective challenges the notion that success is achieved alone, highlighting the importance of relationships, collaboration, and mutual support. A Message to Women and Girls Closing the interview, Professor von der Heyden offers heartfelt advice to women and girls pursuing their ambitions: Be comfortable with who you are. Trust yourself and your abilities. Build meaningful relationships. Accept support when it is offered. Stay open to learning from others. Be adaptable when circumstances change. Work hard, but also be kind—to yourself and to others. Her final message beautifully captures the spirit of the conversation: "Be kind, work hard, and believe in who you are."

This week on Womanity, Dr. Amaleya Goneos-Malka speaks with Professor Catherine Cress who is a Professor of Astronomy at the University of South Africa (UNISA). Her work spans the vast, invisible structures of the universe. Understanding how things work From the outset, Prof Cress reframes astronomy not as distant stargazing, but as a powerful laboratory for understanding the fundamental laws of reality. Her journey begins with a simple but profound curiosity: how does everything work? This curiosity led her from theoretical physics into astronomy, where the universe itself becomes the ultimate testing ground for ideas that cannot be replicated on Earth. Education in all forms Prof Cress has studied at institutions in South Africa, USA, and Germany, and reflects candidly on the role of education, not just formal institutions, but the importance of structured learning, discipline, and intellectual community. While acknowledging that today’s digital world offers unprecedented access to knowledge, she highlights a critical truth: learning in isolation is possible, but rarely optimal. Prof Cress makes a compelling case for the transferable skills gained from studying astronomy, positioning it as the “original data science.” She highlights how skills developed in astronomy, such as big data analysis, AI, computational modelling, translate directly into industries from retail to healthcare. Women’s roles in astronomy A particularly compelling thread in the interview is the role of inspiration and representation. Drawing on figures like Marie Curie and Vera Rubin, Prof Cress reveals how reading and understanding “imaginary mentors” shaped her resilience. She also uncovers the often-overlooked contributions of early female astronomers, women who, despite being sidelined as “computers,” made foundational discoveries that still underpin modern science. Prof Cress notes significant progress has been made for female representation in astronomy, while acknowledging that adjacent fields like physics and supercomputing still lag behind. She also addresses the need for scientists in Africa to believe in their own unique contributions to scientific discovery and pursue their research streams. She shares some of her research into dark matter. Using vivid analogies, she explains how astronomers “look back in time” using light that has travelled billions of years, compressing cosmic history into a scale that reveals just how fleeting human existence is. For example, if the age of the universe was compressed into one year, then all of human history would sit in the last 21 seconds of the year. We explore South Africa’s growing role in global astronomy through projects like MeerKAT and the Square Kilometre Array. Prof Cress frames these not just as scientific achievements, but as catalysts for African collaboration, talent development, and intellectual sovereignty. Success enablers On a personal level, Prof Cress speaks about the support structures that enabled her career, particularly the role of her husband as a primary caregiver, challenging traditional gender norms and offering practical advice to young women navigating similar paths. The interview closes on a note of empowerment. Prof Cress shares a powerful message: don’t underestimate yourself. Whether in science or beyond, she encourages women to claim space, seek support, and pursue their curiosity with confidence. Tune in for more…

This week on Womanity, Dr. Amaleya Goneos-Malka speaks with astrophysicist Dr. Kenda Knowles, Senior Research Fellow at Rhodes University and researcher at the South African Radio Astronomy Observatory. She shares the story of how curiosity, resilience, and collaboration can open pathways to understanding the universe. Stargazing the future Dr. Knowles’ fascination with the cosmos began long before she imagined becoming a scientist. Growing up on the outskirts of Johannesburg and later KwaZulu-Natal, she had access to the kind of dark night skies that spark wonder. Navigating choices through elimination Her academic path was anything but predetermined. In high school, she knew mostly what she didn’t want to do. Instead of following the traditional routes expected of strong students, she gravitated toward physics because of its ability to explain how the world works. A computational physics programme at the University of KwaZulu-Natal ultimately gave her the perfect combination of scientific exploration and practical skills in computing. It was during these studies that she first encountered the groundbreaking Square Kilometre Array (SKA) project, an introduction that would steer her toward radio astronomy and shape the course of her career. Funding mechanisms make education accessible Funding opportunities played a decisive role in enabling her journey. Through the Human Capital Development programme linked to South Africa’s radio astronomy initiatives, Dr. Knowles gained the financial support needed to pursue postgraduate research and expand her academic networks. She emphasises that such programmes are not merely financial assistance, they are essential mechanisms that unlock opportunities for talented students who otherwise might never access scientific careers. Networks unlock opportunities Equally important were the relationships she built along the way. Mentorship and collaboration proved pivotal, especially early in her research career. One supervisor encouraged her to explore different research directions and connected her with experts around the world, enabling her to learn specialised skills and build an international network. These collaborations, she notes, are at the heart of modern astronomy, where discoveries depend on global teams working together rather than competing in isolation. Democratising scientific findings for global progress A defining milestone in Dr. Knowles’ career came in 2021 when she led an international team releasing a vast dataset from the MeerKAT Galaxy Cluster Legacy Survey. The MeerKAT telescope, situated in South Africa’s Karoo desert, is one of the world’s most sensitive radio telescopes. By observing more than a hundred galaxy clusters, the survey created an unprecedented window into some of the universe’s largest gravitationally bound structures. Galaxy clusters serve as cosmic laboratories. Studying them reveals how galaxies evolve in dense environments, how enormous magnetic fields behave across intergalactic space, and how extreme events—such as massive cluster mergers—shape the large-scale structure of the universe. By making this extensive dataset publicly available, Dr. Knowles and her colleagues ensured that researchers across the world could explore it, dramatically multiplying its scientific impact and helping democratise access to cutting-edge astronomical data. The scale of modern astronomy also means grappling with enormous volumes of information. As observatories like the James Webb Space Telescope and future surveys begin producing data on billions of galaxies, artificial intelligence and machine learning are becoming essential tools. These technologies allow scientists to sift through vast datasets and identify unusual or transformative phenomena that might otherwise remain hidden. Yet Dr. Knowles cautions that while AI is powerful, researchers must remain thoughtful about when and how to use it—it is not always the right solution for every problem. Building future scientists and unblocking systemic barriers Beyond research, Dr. Knowles is deeply committed to building the next generation of scientists. She regularly speaks to school students, runs skills-development workshops, and encourages young researchers to explore opportunities such as internships and vacation projects that allow them to experience scientific research firsthand. Her message to aspiring astronomers is practical and empowering: study mathematics and physics, seek mentorship, and take initiative in exploring the field. The conversation also explores the status of women in astronomy. While the field has made notable progress, sometimes reaching near gender parity among students, women remain underrepresented at the most senior academic levels. Dr. Knowles attributes this partly to systemic issues such as unequal administrative burdens and the challenges of balancing family responsibilities with the demanding “publish or perish” culture of academia. Addressing these barriers, she argues, requires conscious institutional change, mentorship structures, and supportive policies that allow talented women to progress in their careers. As the interview concludes, Dr. Knowles offers a powerful piece of advice to young women and girls: don’t place yourself in a box. She recalls a formative moment when a teacher challenged her for limiting herself by believing she was only “a science student.” That conversation inspired her to push beyond those self-imposed boundaries, an experience that eventually led her to unexpected achievements, including a creative writing award in her final year of school. Her takeaway message is: curiosity, creativity, and courage often matter more than predefined paths. By remaining open to possibilities and willing to explore beyond perceived limits, the next generation of scientists may not only discover new truths about the universe, but also new dimensions of their own potential.

This week on Womanity, Dr. Amaleya Goneos-Malka speaks with Dr Sarah Pedretti, Principal Scientific Officer at the University of Cape Town Lung Institute. Dr Pedretti traces her academic path from France and Switzerland to South Africa, highlighting how international collaboration, mentorship, and intellectual curiosity led her to Cape Town. What began as a one-year postdoctoral opportunity evolved into a long-term commitment to African health research. Collaboration Over Competition: How Science Truly Advances Dr Pedretti challenges the myth of the lone scientist, explaining that modern research depends on collaboration across borders, disciplines, and institutions. She reflects on the importance of global conferences, shared data, and collective problem-solving—especially in a world where funding is scarce and duplication of research wastes precious resources. Inside the UCT Lung Institute: Research from Patient to Cell At the UCT Lung Institute, research is deeply integrated with patient care. Dr Pedretti explains how clinical consultations, paediatric allergy services, and clinical trials feed directly into laboratory science. Her work spans the entire value chain—from real patients and clinical symptoms to cellular mechanisms—ensuring that research outcomes remain grounded in lived health realities. Why Allergies Are on the Rise With nearly one-third of South Africans expected to experience an allergic condition in their lifetime, Dr Pedretti unpacks why allergies are increasing. Environmental factors such as pollution and urbanisation intersect with improved awareness and diagnosis. Alarmingly, up to 40% of allergy sufferers are children, making this a growing public health concern. The Hidden Danger: Allergic Reactions to Medication A major focus of Dr Pedretti’s research is drug-induced allergic reactions—particularly to hypertension, HIV, and TB medications. These reactions are often overlooked because patients assume prescribed medicine cannot be the source of harm. Her work aims to identify genetic and biological markers that could one day predict adverse reactions before treatment begins, potentially saving lives. Women, Hormones, and Immunity The conversation explores why women are more prone to allergic and immune-mediated conditions after puberty. Hormonal changes linked to menstruation and menopause can intensify symptoms, underscoring the need for gender-sensitive research and treatment approaches in immunology and allergy care. A Critical Skills Shortage: Where Are the Allergists? Despite rising allergy prevalence, South Africa has only 14 trained allergists—most of them based in Cape Town. Dr Pedretti highlights this severe shortage and reflects on why allergy remains an under-recognised medical specialty, despite its growing burden on public health systems. Funding, Gender, and the Real Barriers in Science Contrary to common assumptions, Dr Pedretti notes that gender itself has not been her primary barrier. Instead, funding constraints remain the biggest challenge in scientific careers. She discusses navigating local and international funding bodies, philanthropic foundations, and industry partnerships—emphasising adaptability and openness as survival skills in research. Science with Purpose: From Rooibos to Genomics Among her most fascinating projects is research into rooibos tea, inspired by a local remedy. Early laboratory findings suggest rooibos may reduce allergic responses, leading to clinical trials that could validate indigenous knowledge through scientific evidence. Her broader vision is clear: science must lead to real-world solutions, whether through diagnostics, prevention, or personalised medicine. Education as Empowerment Dr Pedretti reflects deeply on the role of education in shaping her career and worldview. She credits accessible education systems, lifelong learning, and critical thinking as foundations for innovation—and stresses how unequal access to education continues to limit potential, particularly for women in Africa. Success, Integrity, and Passion For Dr Pedretti, success is built on work ethic, honesty, and resilience. She speaks candidly about long hours, failed experiments, and the importance of publishing negative results. Above all, she believes passion—for science, for patients, for impact—is non-negotiable in a demanding field. Standing on the Shoulders of Strong Women The episode wraps up with moving reflections on the women who shaped her journey—her mother, a pharmacist; her postdoctoral supervisor; and the many women leaders she has encountered at UCT. Their example proves that excellence in science and leadership can coexist with family, humanity, and mentorship. Dr Pedretti closes with a powerful call to action: Trust your curiosity. Build your skills. Seek mentors. Don’t wait for permission to lead. The world needs your voice, your ideas, and your vision. Tune in for more…

Dr. Sarah Pedretti – UCT Lung Institute – Limitless

This week on Womanity, Dr. Amaleya Goneos-Malka speaks with Dr Sarah Pedretti, Principal Scientific Officer at the University of Cape Town Lung Institute. Dr Pedretti traces her academic path from France and Switzerlan...

This week on Womanity, Dr. Amaleya Goneos-Malka speaks with Dr Sebastiana Kalula, emeritus associate professor, specialist physician in geriatric medicine, Director of the Albertina and Walter Sisulu Institute of Ageing in Africa, and Co-Director of the International Longevity Centre South Africa at the University of Cape Town. As global life expectancy rises, Dr Kalula unpacks one of the most pressing issues of our time: how to ensure that longer lives are also healthier, dignified, and equitable — especially for women. From Rural Zambia to Global Leadership in Ageing Dr Kalula reflects on her journey from growing up in rural eastern Zambia, supported by parents who valued education despite not having had the opportunity themselves, to qualifying in medicine and eventually discovering geriatric medicine in the UK. What began as a practical career pathway became a calling. She describes geriatrics as a specialty that blends science and humanity — one that looks beyond a single disease to consider the whole person: physical health, mental well-being, social context, and functional ability. Her career has since positioned her at the forefront of ageing research and advocacy across Africa, where the demographic shift toward older populations is accelerating rapidly. Health Span vs. Lifespan: A Critical Distinction One of the most powerful insights from the conversation is Dr Kalula’s emphasis on extending health span rather than simply lifespan. Living longer, she cautions, is not the goal if those additional years are marked by disability and poor quality of life. She explains that while genetics contribute approximately 25% to longevity, the majority of our health outcomes are shaped by social determinants: education, income, access to healthcare, safe environments, and lifestyle choices. The conditions in which we are born, grow, work and age profoundly shape how long, and how well, we live. Her practical advice is clear: Prioritise whole foods over processed diets Stay physically active at every age Protect sleep and manage stress Remain socially connected Invest in preventive healthcare early in life Healthy ageing, she reminds us, is a life-course process, not a switch we flip at 60. The Gendered Reality of Ageing in Africa Dr Kalula explains that women live longer than men, which means they carry a disproportionate burden of age-related conditions such as dementia. But biology tells only part of the story. Lifetime inequalities, such as limited access to education, unpaid caregiving roles, economic insecurity, and widowhood, compound women’s vulnerability in later life. Chronic stress, she explains, elevates cortisol levels, weakens immunity, increases inflammation, and raises the risk of conditions such as diabetes and vascular disease, all of which can contribute to cognitive decline. In the African context, the challenges can be even more severe. Widowed older women often face social exclusion, loneliness, poverty, and in some communities, even harmful stigma. The emotional and psychological toll of these realities can itself increase dementia risk. Dr Kalula calls for stronger legal protections, income security through pensions, age-friendly healthcare systems, and, critically, better age- and gender-disaggregated data to inform policy. Dementia, Vascular Health and Prevention The conversation also tackles dementia — a growing global health concern. Dr Kalula highlights that in Africa, vascular disease (including strokes and poor circulation to the brain) is a major contributor to dementia. This underscores the importance of managing blood pressure, diabetes, and cardiovascular risk factors early in life. She also emphasises the importance of brain stimulation. Education, meaningful work, continuous learning, and challenging routines all help maintain cognitive reserve. The brain, like the body, needs exercise. Leadership, Mentorship and Building Sustainable Success Beyond medicine, Dr Kalula shares powerful reflections on leadership. She speaks about the importance of mentorship at every stage of life, humility in leadership, and building respectful teams where others can flourish.  She is also a member of the African Research on Ageing Network (AFRAN), the Global Aging Research Network (GARN), the South African Geriatrics Society (SAGS) and the International Association of Gerontology and Geriatrics (IAGG Balancing an academic medical career with family life required resilience, clarity of priorities, reliable childcare, and strong support systems at home and work. “No one succeeds alone,” she reflects, emphasising the value of quality friendships and supportive networks. Her philosophy of success moves beyond achievement to sustainability, well-being, and community impact. A Call to Action for Women In her closing message to girls and women, Dr Kalula encourages continuous self-development: Be the best version of yourself wherever you are Seek mentors Keep learning Challenge your mind Compete against yourself, not others Define where you want to be — and work toward it deliberately Ageing, she reminds us, is universal: “We are all getting there, if we are lucky.” The question is whether we will build societies that allow women to age with dignity, inclusion, and vitality.

Dr. Sebastiana Kalula – Specialist Physician in Geriatric Medicine, UCT – Invest in your healthspan

This week on Womanity, Dr. Amaleya Goneos-Malka speaks with Dr Sebastiana Kalula, emeritus associate professor, specialist physician in geriatric medicine, Director of the Albertina and Walter Sisulu Institute of Agein...

This week on Womanity, Dr. Amaleya Goneos-Malka speaks to Dr Claudia Cardoso from the University of Pretoria.  Dr Claudia Cardoso’s interest in veterinary science was ignited when she was 10 years old, watching a local veterinarian diagnose and treat her sick dog, an ordinary consultation that, for a young girl, revealed something extraordinary. In that moment, she witnessed “knowledge in action”— a spark that would shape her life’s path. Dr Cardoso shares what it meant to rebuild her career after immigrating to South Africa without speaking English, navigating professional scepticism in a male-dominated production environment, and persevering Veterinary Science Beyond the Clinic With nearly two decades of experience, Dr Cardoso offers a window into the diverse realities of veterinary work beyond companion animals. Her expertise spans animal health, reproduction, and production systems — areas critical to food security and rural livelihoods. Through university-led outreach programmes, she worked directly with underserved rural communities, providing veterinary care where access is limited or non-existent. She recounts memorable cases where timely intervention, education on nutrition, and preventive health measures helped farmers preserve entire herds, safeguarding both animals and household livelihoods. These stories underscore the vital role veterinarians play in development, sustainability, and social impact. Gender, Expertise, and Earning Trust Veterinary production systems are still widely perceived as male-dominated spaces, particularly at farm management level. Dr Cardoso speaks about moments when her expertise was questioned or her advice challenged, not because of its scientific merit, but because of who she was. Rather than internalising these experiences, she explains how she learned to navigate them with technical rigour, clarity, and evidence-based outcomes. By presenting facts, outlining consequences, and allowing results to speak for themselves, she asserts a powerful lesson: credibility is built through consistency, confidence, and measurable impact. Animal Production, Ethics, and Feeding the World Dr Cardoso demystifies animal production for listeners, explaining why it is central to global food systems. With a growing global population, the challenge is not simply producing more food, but doing so ethically, sustainably, and with respect for animal welfare and environmental limits. She explores how genetics, nutrition, disease prevention, and welfare standards must work together for animals to reach their full potential, and why productivity without care is neither viable nor ethical. Her insights reveal the delicate balance between profitability, responsibility, and long-term sustainability in modern livestock systems. One Welfare: An Interconnected World Central to Dr Cardoso’s philosophy is the One Welfare framework, the understanding that animal welfare, human wellbeing, environmental health, and food security are inseparable. She explains how farmers’ livelihoods are directly tied to the health of their animals, and how crises affecting livestock often place people at personal risk as they attempt to protect what sustains them. Lessons in Resilience, Curiosity, and Purpose Dr Cardoso closes the show with a message to girls and women to remain curious, pursue the education or career that calls to you, and trust that your contribution matters — not only to yourself, but to society at large.

Dr Claudia Cardoso – Animal Production Veterinarian: University of Pretoria – Remain Curious

This week on Womanity, Dr. Amaleya Goneos-Malka speaks to Dr Claudia Cardoso from the University of Pretoria.  Dr Claudia Cardoso’s interest in veterinary science was ignited when she was 10 years old, watching a loc...

This week on Womanity, Dr. Amaleya Goneos-Malka speaks to Dr Nonhlanhla Vilakazi who specialises in palaeo-herpetology and heritage management in the Zoology Department at the University of Johannesburg. Her work uncovers stories from fossils that contribute to new ways of seeing ourselves and our future. Dr Vilakazi takes us beneath the Earth's surface to explore forgotten ecosystems, rare fossil snakes, and the secrets embedded in rock formations that stretch back millions of years. Through her African-centred lens, she explains how ancient species help us understand climate change, biodiversity loss, and the alarming possibility that humanity may be in the midst of a mass extinction event. Beyond the science, Dr Vilakazi is a powerful advocate for reshaping human relationships with misunderstood creatures like snakes, blending scientific insight with Indigenous knowledge systems and cultural narratives. Her storytelling transforms fear into understanding, reminding listeners how deeply interconnected life truly is both past and present. The conversation also highlights her commitment to transforming STEM education. Dr Vilakazi discusses the importance of integrating indigenous worldviews with scientific methods to make STEM relevant and inclusive, especially for young women and learners from under-resourced communities. She speaks candidly about breaking stereotypes in paleontology, the challenges of being one of the few women in fieldwork, and the vital need for family-friendly policies in academia. From groundbreaking discoveries in South Africa, Namibia, and Uganda to cutting-edge AI collaborations that are modernising fossil analysis, Dr Vilakazi’s work pushes scientific boundaries while inspiring the next generation of African scientists. Despite her trailblazing contributions, Dr Vilakazi reminds us that paleontology remains a male-dominated field. One still shaped by the lingering stereotype of the “Indiana Jones” adventurer. She speaks openly about the subtle and overt barriers women face, from doubts about their physical capability to the practical challenges of fieldwork environments that have never been designed with women in mind. Often the only woman on excavation teams, she has had to carve out space. Yet her presence is transformative: her visibility has inspired many of her former undergraduate students, particularly young women, to pursue postgraduate studies in paleontology. Her journey powerfully demonstrates that representation is not symbolic, it's catalytic. When women see someone who looks like them thriving in STEM, entire career pathways become imaginable. The episode culminates in a relatable message to young women across the continent: science is not distant or exclusive; it is present in everyday life, fueled by curiosity, resilience, and the stories we choose to tell about ourselves.
