Dr. Nancy Carnide is a post-doctoral fellow at the Institute for Work & 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, a CIHR Strategic Training Fellowship in Work Disability Prevention. 

Carnide's research interests lie at the intersection between occupational health and safety and pharmaco-epidemiology. They include substance use and mental health problems among working populations. Her research projects have involved analysis of survey and administrative data, as well as systematic reviews. Her doctoral dissertation focused on the use of prescription opioids among workers with work-related low-back pain and their association with work disability. Her emerging program of research builds on this work to examine the use and non-medical use of prescription and recreational central nervous system drugs (including opioids and cannabis) among workers, their risk factors and the workplace consequences of their use.

“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
