Dr. Nancy Carnide
Dr. Nancy Carnide is a scientist at the Institute for Work & Health. She is also an assistant professor in the Division of Epidemiology at the University of Toronto's Dalla Lana School of Public Health.
She has a PhD in epidemiology from the Dalla Lana School of Public Health at the University of Toronto. During her PhD, she was the recipient of a Canadian Institutes of Health Research (CIHR) Vanier Canada Graduate Scholarship and a CIHR Strategic Training Fellowship in Work Disability Prevention.
Carnide's primary program of research involves examining issues at the intersection between occupational health and safety and substance use, including examining the use and non-medical use of prescription and recreational drugs among workers, their risk factors and the workplace impacts of their use. Her research projects have involved analysis of survey and administrative data, qualitative approaches, as well as systematic reviews.
“The gaps in knowledge around the scope, determinants and effects of substance use among workers are vast. Given the current opioid crisis and the move towards cannabis legalization in multiple jurisdictions, including Canada, I cannot think of a more timely area for research in occupational health and safety.” – Dr. Nancy Carnide
