Samuel Veissière is Assistant Professor in the Division of Social and Transcultural Psychiatry, co-director of the Culture, Mind, and Brain program, and Associate Member in the Department of Anthropology.
Dr. Veissière is an anthropologist and psychosocial clinician working at the intersection of psychiatry, cognitive science and the social sciences. His work combines ethnographic, experimental, clinical, evolutionary, contemplative, and psychoanalytic perspectives on human cognition, consciousness, and mental health.
Dr. Veissière has held multiple research grants to study the impact of the Internet on cognition, wellbeing and social relations. His work on social and behavioural dimensions of screen addiction led to one of the first interventions to reduce problematic smartphone use successfully tested in a randomized controlled trial. Past research includes leading experimental studies on social, symbolic, and ritual dimensions of placebo effects, and making original contributions to theoretical models of the co-evolution of cognition and culture that draw on Bayesian brain, active inference, and ecological niche construction paradigms.
His current works examines risk and protective factors against violent radicalization and extremism, with an emphasis on digital, narrative, and gendered dimensions of social polarization.
Dr. Veissière accepts a limited number of honour’s undergraduate, graduate, and post-doctoral students for supervision in Psychiatry, Cognitive Science, Anthropology, and related disciplines on topics related to social media and mental health, social polarization, violent extremism, gender and radicalization, the mental health of men and boys, and the “mental health crisis” of Generation Z. Dr. Veissière currently has no funding to support graduate students.
