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 holds a Canada Research Chair in Drug Policy Research and Evaluation, is a Scientist in the Li Ka Shing Knowledge Institute of St. Michael’s Hospital and ICES, and is 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 200 peer-reviewed articles and over 100 policy reports in this area.  Dr. Gomes also works closely with government regulators at the provincial and national level to develop evidence to inform policies related to opioid use disorder and opioid-related harm through the Ontario Opioid Drug Observatory.  In 2014, she was awarded the Institute for Public Administration of Canada’s Bronze Public Sector Leadership Award in Health and Education to recognize the impact of the ODPRN’s work.
