Proud moment for Dr Matumelo Alice Rafiri as she is conferred with PhD at the Spring Graduation, recognising her research on Artemisia afra. Dr Rafiri’s research is envisioned to advance indigenous knowledge through regional analysis of plant DNA and Bioactive composition.

The Spring Graduation Ceremony at the Central University of Technology, Free State (CUT), not only marked a milestone for over 600 graduates but also celebrated the inspiring journey of Dr Matumelo Alice Rafiri, conferred with a Doctor of Philosophy for her research on Artemisia afra, a medicinal plant widely used in South Africa and Lesotho.

Dr Rafiri, who holds a BSc in Agriculture from the National University of Lesotho and a Master of Science from the University of Pretoria, dedicated her doctoral study to understanding the genetic diversity and bioactive compounds of Artemisia afra. By using advanced DArTseq technology, she analysed accessions from four different agroecological zones, uncovering that the plant’s DNA and bioactive composition varied significantly depending on its origin.

Her findings carry profound implications for the field of indigenous medicine. “I found that the Artemisia from different places is not the same. This study made me very happy because I wanted to help the people who are doing indigenous medicine to know that the ingredients are not the same,” she explained.

Despite challenges along the way, including the disruptions brought by the COVID-19 pandemic, Dr Rafiri pushed through. “The study was challenging because when we were in the middle of it, COVID came, and we just had to take a break. After COVID, the courses we were doing changed, and we had to start again and register again to finish. But I was very happy I managed to publish two articles,” she said with pride.

In reflecting on her journey, Dr Rafiri extended her gratitude to her supervisor, Professor MM Sedibe, “I want to thank my professor for his patience and guidance. His continues support helped us to get to where we are today,” she shared warmly.

Rafiri’s work not only contributes to scientific innovation and public health documentation but also strengthens the recognition of indigenous knowledge systems that continue to shape healthcare and economic development in the region.

As the university celebrates the achievements of its Spring 2025 graduates, Dr Rafiri’s story stands as a beacon of resilience, innovation, and gratitude, a reminder that research rooted in tradition can shape the future of science and society.
