Theodore D. Cosco joined the Oxford Institute of Population Ageing in 2016 as a Research Fellow.

Dr. Cosco is an Associate Professor in the School of Public Policy at Simon Fraser University, Canada, where he directs the Precision Mental Health Lab. 

He is a Chartered Psychologist with the British Psychological Society and has postgraduate training in research methods and psychometrics from Trinity College Dublin and a PhD in Epidemiology from the University of Cambridge.

His research sits at the intersection of gerontology, mental health, epidemiology, psychology, and public policy. His work examines psychological resilience, mental health and wellbeing in later life, social isolation, cognitive ageing, and health inequalities using longitudinal and life-course methods. His research also encompasses digital and virtual models of care, mental health service delivery, psychometric measurement, evidence synthesis, and knowledge mobilization.

Across this work, Dr. Cosco has developed an interdisciplinary research programme focused on identifying factors that support healthy ageing and translating evidence into interventions, services, and policies that improve health and wellbeing across the life course.
