Martin Williams is a postdoctoral research fellow in structural biology and medicinal chemistry at Monash University, currently working primarily on novel antibiotic research. His interests in psychology and pharmacology have led him towards the multidisciplinary study of psychoactive compounds and their roles in contemporary society. He is a founding member of Entheogenesis Australis (EGA), a non-profit educational/harm-minimization association focused on understanding the historical use and societal impacts of medicinal plants and chemicals. Since 2004, EGA has organized annual conferences and symposia, hosting prominent Australian and international thinkers in the field. To complement the educational brief of EGA, Martin and colleagues established PRISM Inc (http://prism.org.au), a health-promotion charity that aims to coordinate Australian contributions to global academic research into the wide-ranging medical and psycho-social applications of psychoactive drugs.
