Professor Yasien Sayed is a Full Professor of Biochemistry at the University of the Witwatersrand, Johannesburg, South Africa, where he has built a distinguished academic and research career spanning three decades. He holds a BSc (1995), BSc Honours (1996), and PhD (2001), all conferred by the same institution. Professor Sayed's research expertise encompasses protein structure-function relationships, enzyme kinetics and dynamics, biological thermodynamics, protein folding and stability, structural biology, computational biology, and rational drug design. His current research programme is focused on the molecular characterisation of clinically relevant proteases, most notably HIV-1 and SARS-CoV-2 proteases, with the aim of informing the development of novel therapeutic agents. He serves as Director of the Protein Structure-Function Research Laboratory (PSFRL) and Deputy Head of the School of Molecular and Cell Biology. In these roles, he provides strategic and scientific leadership while contributing actively to governance at school, faculty and institutional levels. Professor Sayed has authored/co-authored more than 90 peer-reviewed articles in high-impact international journals and is widely recognized for his contributions to the understanding of conformational dynamics and protein-drug interactions. Professor Sayed has a strong commitment to postgraduate education and human capital development, having successfully supervised numerous MSc and PhD candidates, many of whom
