I am the Analytical Lead at the Media Ecosystem Observatory at McGill University, and a member of the Chaire de recherche du Québec sur la démocratie, le vivre ensemble et les valeurs communes au Québec. I hold a Ph.D. in political science from McGill and completed a postdoctoral fellowship in the Program in Quantitative Social Science at Dartmouth College.
I study the health of the political information environment: what information citizens actually encounter, and how it shapes what they believe and how they act. Most of my work concerns mis- and disinformation, political microtargeting, perceptions of election integrity, trust, and polarization in Canada, Quebec, and the United States.
My work draws on surveys, news content, web browsing data, social media data, and audits of AI chatbots.
I also spend a good deal of time explaining this research outside the academy, in French and in English.
