Stein is Professor and Chair of the Department of Psychiatry and Mental Health at the University of Cape Town, and Director of the South African Medical Research Council's Unit on Risk and Resilience in Mental Disorders. His work ranges from basic neuroscience, through clinical research, and on to epidemiological studies. He is enthusiastic about clinical practice and scientific research that integrates concepts and data across these different levels, including in the context of low and middle-income countries. He is a recipient of the Collegium Internationale Neuropsychopharmacologicum's Max Hamilton Award for his contributions to psychopharmacology, and of its Ethics in Psychopharmacology Award. Ronald C.
