Prof Nkengafac Villyen Motaze (M.D, M.Sc., PhD) is a Cameroonian medical epidemiologist currently based at Medicine Usage in South Africa (MUSA). In 2007, Villyen completed his medical studies in Yaoundé, Cameroon and worked for four years in the North West province of Cameroon before moving to Cape Town in 2012 where he completed his masters in Clinical Epidemiology at Stellenbosch University.

My interests are in behavioural neuroscience and neuro- and psychopharmacology, with a special interest in anxiety and stress related disorders, including depression, post-traumatic stress disorder (PTSD), obsessive compulsive disorder (OCD) and schizophrenia. My research focuses on mechanisms of synaptic and cellular signalling, and especially their relevance in the pathology and pharmacology of stress-related disorders.
