Dr. Tara Gomes is an epidemiologist and Principal Investigator of the Ontario Drug Policy Research Network (ODPRN), a provincial network of researchers with expertise in pharmaceutical utilization, outcomes and policy who rapidly conduct research for drug decision-makers in Ontario and across Canada.  She is also a Scientist in the Li Ka Shing Knowledge Institute of St. Michael’s Hospital and the Institute for Clinical Evaluative Sciences and an assistant professor at the University of Toronto.  Her research is focused on pharmacoepidemiology, drug safety and drug policy research leveraging large, administrative databases, and she has published over 125 peer-reviewed articles and over 50 policy reports in this area.

Dr. Gomes has worked closely with the Ontario Ministry of Health and Long-Term Care and the Canadian Network for Observational Drug Effect Studies (CNODES) to develop evidence to inform policies related to opioid use and abuse in Ontario and more broadly across Canada.  She has also served as an expert for the US Food and Drug Administration and the US Department of Transportation in discussions related to opioid policies and regulations. In 2014, the ODPRN was awarded the Institute for Public Administration of Canada’s Bronze Public Sector Leadership Award in Health and Education.
