Joséphine Lechartre is a PhD student in political science and peace studies at the University of Notre Dame, where she specializes in the study of transitional justice policies, war legacies, and post-conflict violence. She is currently a research affiliate of the Kellogg Institute's Notre Dame Violence and Transitional Justice Lab (V-TJLab).

Her main regional focus is Latin America. Lechartre's work has been supported by a five-year Richard and Peggy Notebaert Fellowship, a John Darby Fellowship, a research grant from the Kellogg Institute, and several grants from the Kroc Institute for International Peace Studies. Her research explores the impact of wartime violence on post-conflict social mobilization. Joséphine relies on a mix of qualitative and quantitative methods involving interviews, archive work and social network analysis.

Joséphine received her BA and MA cum laude from the Institut d’Etudes Politiques de Paris (Sciences Po Paris).
