Honorary Research Fellow
Current work and interests
Samantha Hajna is an Honorary Research Fellow. Her research focuses on the development and evaluation of physical activity interventions among older adults. With expertise in the application of Geographic Information Systems and GPS monitoring to health research, Samantha is currently leading several projects aimed at understanding the role that environments play in health behaviours and health outcomes.
Background and experience
Prior to joining the Population Health Interventions, Sam was an Honorary Research Fellow in the Prevention of Diabetes and Related Metabolic Disorders in high risk groups programme. Samantha completed her BSc and MSc degrees at Brock University (ON, Canada) and was awarded a PhD in Epidemiology from McGill University (QC, Canada). Some of the studies that Samantha is currently involved with include the EPIC-Norfolk Study, UK Biobank, and the Fenland Study.
