Sharmistha Mishra, MD, MSc, PhD is an infectious disease physician and epidemiologist, and a Tier 2 Canada Research Chair in Mathematical Modeling and Program Science. She worked in Sierra Leone with the WHO during the West Africa Ebola outbreak in 2014-2016. Her research focuses on disentangling sources of heterogeneity in risks of onward transmission and is grounded in the implementation of adaptive public health strategies tailored to meet the needs of populations at differential risks. Since March 2020, she and the research lab have been working with Toronto Public Health, Safehaven, Chiefs of Ontario; and hospitals, shelters, and long-term care homes in the Greater Toronto Area to conduct data-driven epidemic modeling around sources of heterogeneity in the spread of SARS-CoV-2 with a focus on examining and evaluating population- and place-specific interventions. The lab is also conducting observational epidemiology and SARS-CoV-2 transmission modeling projects with colleagues across 5 provinces in Canada, with a focus on heterogeneity and structural inequities as mediators of epidemic spread. Sharmistha is also supporting the CanCOGen Implementation Committee as an infectious disease epidemiologist.
