Donald A. Lloyd

Emeritus Research Associate Professor

A social epidemiologist trained at the University of Toronto, Donald A. Lloyd has worked on several large-scale community-based studies in Canada and Florida. His work focuses on life course processes that are associated with differential risk for mental health and substance-use problems across sociodemographic groups.

His recent projects address the role of lifetime cumulative exposure to major and potentially traumatic events in the risk for initial onset of psychiatric disorders and addictions. His published research documents the important distinction between proximal and distal exposure to stressful events and their independent contribution to the risk for subsequent disorder. Prior to joining the Trojan Family, Dr. Lloyd developed and led graduate seminars in the burgeoning field of life course epidemiology.
