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”.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
