Sean Nossek

I am a Ph.D. Candidate in Political Science at Yale University, where I study international and comparative political economy with a focus on the politics of trade. My research explores how globalization affects the market power of firms, and the relationship between market power and the political power of firms and workers. 

I graduated with First Class Honours from McGill University with a B.A. in Honours International Development Studies in 2018. I received an M.A. in Political Science from McGill University in 2020.  I have also worked as a researcher in the private sector and IO/NGOs, including at Data Sciences, a Montreal-based political consultancy, at the UN Environment Programme, and at the Media Ecosystem Observatory. I have been a Teaching Fellow, Teaching Assistant, and Co-instructor for many courses on international relations and quantitative research at Yale University and McGill University.

I am on the 2026-2027 job market.
