In a proud moment for Sefako Makgatho Health Sciences University (SMU), Dr Nana Millicent Duduzile Buthelezi has been awarded a Y2 rating by the National Research Foundation (NRF) — a distinction reserved for promising young researchers under 40 who have held a doctorate for fewer than five years and are recognised for their potential to establish themselves as leading academics within the next five years.
The NRF rating is one of South Africa’s most rigorous measures of research excellence, based on international peer review and the quality, originality, and impact of a scholar’s research outputs. For Dr Buthelezi, this recognition is more than a personal achievement — it is a validation of years of dedication to sustainable science and a catalyst for future innovation.
“Receiving recognition from the NRF is a significant milestone in my career, symbolising and validating my academic growth,” she said. “It has increased my visibility and credibility within the academic community, opened doors for collaboration, and encouraged me to pursue impactful, innovative projects.”
Buthelezi’s academic journey is exceptional. Holding two PhDs — one in Horticultural Science and another in Botany — she has focused her research on environmental sustainability, green nanotechnology, and postharvest biology. Her work explores eco-friendly agricultural solutions, including nanofertilisers, biostimulants, and nanocomposite coatings that extend the shelf life of fresh produce while reducing environmental damage.
Her passion for sustainable agriculture was sparked by witnessing the effects of environmental degradation, climate change, and food waste. “My research addresses two pressing global challenges — postharvest losses and environmental decline,” she explained. “By developing green technologies, we can improve crop yields, enhance food security, and protect our planet for future generations.”
At SMU, Buthelezi credits her department and mentors for providing a nurturing environment that has allowed her to thrive. “The support from Prof Piet King, our Head of Department, has been instrumental. SMU has fostered a collaborative culture that promotes interdisciplinary research and innovation,” she said.
The NRF Y-rating underscores Buthelezi’s growing influence in the scientific community. Her research not only strengthens SMU’s standing as a research-intensive institution but also contributes directly to South Africa’s broader mission of sustainable development and food security.
Currently, she is leading projects on green nanotechnology in collaboration with the Agricultural Research Council (ARC) and other universities. Her team, which includes MSc and PhD students, is developing environmentally friendly nanomaterials such as zinc oxide, magnesium oxide, and titanium dioxide nanoparticles — innovations that promise to revolutionise modern agriculture.
Beyond her research, Buthelezi is passionate about mentorship. She guides postgraduate students through hands-on training, peer mentorship, and publication in high-impact journals. “The NRF rating has strengthened my commitment to mentoring emerging scholars,” she noted. “Our next generation of scientists must be equipped to think critically, research ethically, and innovate sustainably.”
As for her future, Buthelezi remains ambitious and forward-looking. “This milestone inspires me to push the boundaries of green science further,” she said. “Ultimately, I hope my work leaves a legacy of sustainable agriculture that balances productivity with environmental stewardship.”
With her recognition, Buthelezi joins the growing cohort of SMU researchers placing the university on the map as a leader in health sciences, agricultural innovation, and environmental resilience — a shining example of how world-class research can begin right here at home.
