She is a Full Professor (professeure titulaire) in the Department of Family & Emergency Medicine at the Université Laval, in Quebec City, Canada.
[1] Witteman is the Canada Research Chair (Tier 2) in Human-Centred Digital Health (Santé numérique axée sur les personnes).
[1][3] In 2019, Witteman led a study, published in The Lancet, which found that when grant reviewers at the Canadian Institutes of Health Research primarily assessed the applicant as a scientist (rather than their proposed research), there were significant differences in success between male (13.9% success) and female (9.2%) principal investigators.
[9][10] In June 2020, Witteman received a Canadian Institutes of Health Research grant ($311,296) to investigate how Canadians perceive COVID-19 risk-reduction messages (such as the two-meter rule), and create digital health materials, such as videos and web applications, to help people better understand the science about COVID-19.
[13] She has spoken about different aspects of academia and the COVID-19 pandemic for various media outlets, including gender bias in academic grant applications, ableism, vaccine hesitancy, and the confusing COVID-19 vaccine roll-out for people with chronic health conditions in Quebec.
