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.
