Biography

Ann Burchell is an epidemiologist and Scientist with the Department of Family and Community Medicine and Li Ka Shing Knowledge Institute at St. Michael’s Hospital, Toronto. She holds degrees in epidemiology from the University of Toronto (MSc) and McGill University (PhD) and has academic appointments as Assistant Professor, Dalla Lana School of Public Health, University of Toronto; Adjunct Professor, Division of Cancer Epidemiology, McGill University; and Adjunct Scientist, Institute for Clinical Evaluative Medicine, Toronto.

Dr. Burchell’s research program focuses on the epidemiology of human immunodeficiency virus (HIV) infection, human papillomavirus (HPV), syphilis, and other sexually transmitted infections (STIs). She has a particular interest in generating evidence for effective, efficient, and practical primary and secondary prevention strategies for control of STIs and STI-related cancers in marginalized communities.

She has extensive methodological experience in the design and implementation of: observational longitudinal studies with primary and secondary data; sexual behavior and health-access questionnaires; natural history studies using laboratory markers of infection; and, most recently, pragmatic randomized trials for HPV prevention and improved screening for syphilis, cervical and anal cancer. She currently holds a New Investigator award from the Canadian Institutes of Health Research.
