About Dr. Catherine Trask

Dr. Catherine Trask is a Canada Research Chair in Ergonomics and Musculoskeletal Health (Tier II), and an Associate Professor in the Canadian Centre for Health and Safety in Agriculture within the College of Medicine at the University of Saskatchewan.   She was trained as an Occupational Hygienist with a focus in Ergonomics at the University of British Columbia. Her research spans ergonomics, musculoskeletal injury surveillance, exposure assessment and sampling strategies, as well as evaluation of workplace interventions. As Director of the National Agricultural Industrial Hygiene Laboratory's Ergonomics Lab, she leads injury prevention projects in several industries, with particular focus on agricultural environments such as grain farming and intensive pork production.
