Zoë Dubus is a post-doctoral researcher in history of medicine at the College of Arts and Science, Department of History, USASK, Canada. She obtained a Banting funding from the SSHRC for this research, which aims to rediscover the pioneering work of three women therapists who proposed new ways of practicing LSD-assisted psychotherapy in the 1950s-1970s, before being invisibilized. More generally, her research deals with the transformations in medical practices and health policies associated with the use of psychotropic drugs, from the 19th century to the present day. It focuses on understanding the relationship between doctors and products that modify consciousness and sensitivity, conceived alternatively as innovative medicines or as toxic substances.
