Research Interests

  • Social Epidemiology
  • Population Health Intervention Research
  • Urban Health
  • Women’s Health

Dr. O’Campo is Tier 1 Canada Research Chair in Population Health Intervention Research with an established program of research focused on the impact of social policies and poverty alleviation on the well-being of urban populations. As an innovator she has advanced methodologies and generated strong evidence to inform the design of solutions to reduce urban health inequities. Relying mainly on primary data collection for her research she has received over $65 million in grant funding as PI or co-PI from national and international funding bodies.

Dr. O’Campo’s scholarship has shaped the development of the field of Social Epidemiology over the past two decades. She pioneered, in the mid-1990s, the now firmly established global research agenda concerned with the impact of residential neighbourhood conditions on health.  Her groundbreaking research is among the very first and most cited published work on this topic.

Dr. O’Campo’s unique scientific contributions which place her at the forefront of her field have been the pursuit of theoretical and methodological innovations in social epidemiology including multilevel statistical modeling, concept mapping, explanatory case studies, developmental evaluation, and evaluation methods drawing from Realist philosophy of science.  Along with community and program partners, Dr. O’Campo has been a leader of population health intervention research (or the science of solutions) and has contributed to Canada’s role as a global leader in this area.

She is an outstanding mentor who has supervised and trained well over 100 students and fellows. Her esteemed career has been widely recognized for research and mentorship starting five years post-graduation with a Young Professional Award from the American Public Health Association, a mid-career award from the US Institute of Medicine, a mid-career award for excellence in teaching, the Advancing Epidemiologic Knowledge award recognizing career contributions from a 16-organization coalition in the US and over six awards for her superb teaching and mentoring. She is both Fellow of the Royal Society of Canada and the Canadian Academy of Health Sciences.
