Why working at PHO is important to me:

"Working at PHO is important to me because it is the hub that brings together public health practitioners, researchers, and educators for all of Ontario. As a public health researcher in Ontario, it is simply the place to be."

    • Assessing the health and economic burden of infectious diseases.

    Current PHO research activities

    • Estimating influenza vaccine effectiveness against laboratory-confirmed serious outcomes in high-risk populations (older adults, young children, individuals with chronic conditions).
    • Examining the association between laboratory-confirmed influenza and acute cardiovascular events (myocardial infarctions and ischemic stroke).
    • Evaluating the effectiveness and cost-effectiveness of health care worker vaccinate-or-mask influenza prevention policies Canadian Immunization Research Network (CIRN) Provincial Collaborative Network (PCN): assessing pertussis vaccine effectiveness.
    • Estimating longitudinal health care costs for infectious diseases using administrative data.
    • Provide expertise in epidemiological study design and analysis, and facilitate access to the extensive population-based data holdings at the Institute for Clinical Evaluative Sciences, for studies on the health impacts of air pollutants, the epidemiology of mycobacterial infections, and the epidemiology and economic burden of viral hepatitis.
