DONALD LLOYD joined USC's School of Social Work in 2010; he is a social epidemiologist with training in cultural anthropology and medical sociology. He has worked on several large-scale community-based studies in Canada and Florida. To date his work has been cited in 900 refereed publications, with work on the epidemiology of social stress receiving the greatest attention. His recent work focuses on life course processes that are associated with differential risk for psychiatric illness and substance use disorders across sociodemographic groups. Dr. Lloyd's work in the Roybal Institute builds upon his research at the nexus of aging, disablement, and mental health.
Additional projects have addressed the role of lifetime cumulative exposure to major and potentially traumatic events in the risk for initial onset of major depression, post-traumatic stress disorder, alcohol dependence and drug dependence disorder. 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. His recent research examines trajectories of exposure to stressful events over the life course, including factors that affect the shape of the exposure profile and the health outcomes that are associated with distinct trajectories. Prior to joining the Trojan Family, Dr. Lloyd conducted a popular graduate seminar in life course epidemiology.
