Monray E. Williams is an Associate Professor in Biochemistry within the Biomedical and Molecular Metabolism (BioMMet) research entity at the North-West University, Potchefstroom, South Africa. He is currently a Fulbright Visiting Research Scholar at the University of Texas Medical Branch, Galveston, United States.

He is a Principal Investigator within the NeuroMetabolism Research Group, established in 2024 as a sub-programme of the BioMMet focus area. His research programme integrates neurobiology, immunology, and virology to investigate the mechanisms through which HIV-1 affects the brain, with a focus on neuroinflammation, viral protein diversity, and immune-metabolic dysregulation in sub-Saharan African populations.

His work advances subtype-aware neuroHIV frameworks, examining how HIV-1 subtype C viral diversity may influence neurocognitive outcomes. The programme integrates viral sequence analysis with immune and metabolic profiling, highlighting links between subtype-specific amino acid variation in viral proteins such as Tat and Vpr, inflammatory pathways and the tryptophan-kynurenine axis associated with neurocognitive impairment. It also relates these molecular mechanisms to clinical and neurocognitive outcomes in South African cohorts, addressing gaps in population-level evidence on subtype-specific neuropathogenesis. This research is supported by national and international collaborations across neurovirology, immunology and computational biology.

He contributes to study design, hypothesis development and interdisciplinary data integration across molecular, clinical and computational domains. His Fulbright Visiting Research Scholar appointment at the University of Texas Medical Branch enables collaboration using advanced in vitro blood-brain barrier models to investigate subtype-specific neuroinflammatory and neurovascular mechanisms, further extending the translational scope of this work. Monray serves as Secretary and Council Member of the South African Society for Biochemistry and Molecular Biology (SASBMB) and is an Executive Council Member of the Southern African Neuroscience Society (SANS).
