Two University of the Free State (UFS) academics have been elected to the Academy of Science of South Africa (ASSAf), joining the ranks of the nation’s most distinguished scholars. Prof Serges Kamga, Dean of the Faculty of Law, and Prof Carlien Pohl-Albertyn, NRF-SARChI Research Chair in Pathogenic Yeasts and Professor of Microbiology, were recently recognised for their outstanding contributions to research, scholarship, and the advancement of knowledge.

In addition, Dr Mutshidzi Mulondo, an academic in the Division of Public Health within the Faculty of Health Sciences who recently made history as the first academic from the UFS to be inaugurated to the prestigious Global Young Academy – a network institution of the United Nations Scientific Advisory Board – was selected to the South African Young Academy of Science (SAYAS) as one of the top young scholars recognised for engaged scholarship and scientific contribution. SAYAS provides early-career researchers with a platform to influence science, policy and innovation across South Africa and the continent.

Prof Vasu Reddy, Deputy Vice-Chancellor: Research, Innovation and Postgraduate Studies, who is also a member of the academy and a member of the ASSAf Council, says: “Membership in the Academy of Science of South Africa is a hallmark of scholarly distinction. It is to be entrusted with the stewardship of knowledge. More than this, it is an affirmation that one’s work resonates nationally and globally in advancing knowledge for societal good.”

 

Celebrating UFS excellence

Since its inauguration in 1996 by former President Nelson Mandela, ASSAf has championed the use of science for the benefit of society. Its mandate spans all fields of scientific enquiry, promoting scholarly excellence, evidence-based solutions to national challenges, and international collaboration. With these recent elections, 23 UFS staff members now hold membership of ASSAf, reflecting the university’s growing national and global research impact.

SAYAS, established under ASSAf, empowers young scientists to shape scientific dialogue, influence policy, and tackle pressing societal challenges. Its mission is to create a vibrant community of early-career researchers driving innovation, education, and sustainable development.

Prof Reddy also remarks: “ASSAf and SAYAS are platforms where excellence meets responsibility, purpose, and service. It is, in fact, a call to shape the scientific imagination of the nation, to mentor with purpose, and to lead with intellectual generosity. My heartfelt congratulations to our colleagues who have received recognition from the academy. You make the UFS proud.”

 

Prof Serges Kamga: Human rights and inclusive development

For Prof Serges Kamga, being elected to ASSAf is both an honour and a validation of his lifelong commitment to the advancement of human rights and social justice. “My election demonstrates that I am on the right track in terms of scientific knowledge and activity to remove barriers between people and obstacles to full development of their intellectual capacity,” he says.

His research focuses on the human right to development, socio-economic inclusion, and equality, particularly for vulnerable groups such as persons with disabilities. “I rely on scientific evidence to stress the need to build an equalitarian world, a world without barriers to the full development of human potential,” he explains. Personal experience in witnessing poverty and underdevelopment across Africa inspired him to ask: “If development is a human right inherent to all, why are we poor in Africa? Who pulls the strings of poverty nationally and globally, and why?”

Prof Kamga intends to use his ASSAf membership to strengthen interdisciplinary collaboration and foster responsible societal futures. “My engagement with colleagues will seek ways to break down artificial barriers between disciplines, institutions, and sectors to foster groundbreaking discoveries at the intersection of fields. Modern lawyers should bridge the gap between theory and practice to ensure relevance to their environments.” He also hopes to guide the next generation of legal scholars to combine strong theoretical foundations with practical relevance: “They should connect across disciplines, generate new knowledge, and advance innovative, sustainable solutions to society’s contemporary and future challenges.”

 

Prof Carlien Pohl-Albertyn: Exploring the frontiers of fungal biology

Prof Carlien Pohl-Albertyn describes her election as “a meaningful recognition of my contributions to the national research landscape”. Her research investigates bioactive lipids in pathogenic fungi, focusing on molecules such as oxylipins and prostaglandins that influence fungal virulence and host-pathogen interactions. “By exploring these pathways, I hope to uncover novel targets for antifungal therapies, especially in the context of rising antifungal resistance,” she says. Her work has already shown how polyunsaturated and marine-derived fatty acids can inhibit biofilm formation, a key virulence factor, in Candida species.

Her research also has public health significance through the South African Fryer Oil Initiative (SAFOI), which monitors the quality of frying oils nationwide. “My research on fungal lipids and edible oils is connected by a central theme: understanding how lipids influence health, whether through microbial pathogenicity or human nutrition,” she explains.

Mentorship is equally central to her work. “I foster collaboration and encourage open exchange of ideas, with shared credit and authorship as a non-negotiable principle. Students are supported to publish in reputable journals and present at both local and international conferences, and I actively connect them with global collaborators to help them see themselves as equals on the international stage. Over the years, I have had the privilege of mentoring a diverse group of students and postdocs (many of them first-generation scholars) who have gone on to lead in academia, industry, and government. Our current group reflects a rich diversity of cultures, languages, and identities, and I am committed to continuing the tradition of care and excellence that was instilled in me by my own mentors.”

Prof Pohl-Albertyn is optimistic about future discoveries in her field. “Advances in lipidomics and systems biology are allowing us to study bioactive lipids with increasing precision. Understanding how fungi adapt their lipid pathways in response to environmental pressures, such as climate change or antimicrobial exposure, could reveal new strategies to combat fungal infections and predict emerging pathogens.” She also hopes to use her ASSAf platform to advocate for greater awareness and investment in fungal disease research and to promote equitable access to research funding for African scientists.

 

Dr Mutshidzi Mulondo: Public mental health in a digital age

Dr Mutshidzi Mulondo’s research focuses on mental health, particularly the implementation of digital strategies for public mental health. Mental health, a silent pandemic of our generation, continues to receive limited attention. “My current research looks at digital public mental health strategies, allowing for holistic care and support, particularly in lower- and middle-income countries.” This research is an effort to advance public health strategies that prioritise mental health and health equity.

Dr Mulondo sees the academy as a platform to influence national scientific dialogue and shape policy through emerging efforts such as science diplomacy. “This opportunity allows me to impact policies, specifically in public health, for the betterment of people’s lives. Young scientists need more opportunities to interact with established scientists for intergenerational collaboration. This platform provides young scientists with mentorship as future national and global leaders. Furthermore, the platform provides young scientists with access to other leading scholars for interdisciplinary collaboration to address some of the wicked challenges of our generation.” 

Through SAYAS, Dr Mulondo hopes to contribute to programmes that support the growth of young scientists, increase public understanding of science, and foster sustainable development. “I look forward to participating in these efforts to better place our nation and continent.”

 

A growing legacy of scholarship

The election of Prof Kamga, Prof Pohl-Albertyn, and Dr Mulondo underscores the UFS’ commitment to nurturing excellence across disciplines – from law and the humanities to microbiology and public health. Through the work of ASSAf and SAYAS members, the UFS continues to shape the scientific and academic landscape of South Africa, supporting a vibrant, inclusive, and forward-looking research community. Prof Reddy also emphasises that “recognition by a national academy is a powerful endorsement of one’s scholarly journey. It signals that your voice matters in shaping the intellectual, innovation, and developmental landscape as we aspire to create responsible societal futures”.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
