Meghan Garrity is a Postdoctoral Fellow in the International Security Program at the Harvard Kennedy School, Belfer Center for Science & International Affairs and a former Peace Fellow with the U.S. Institute of Peace. She received her Ph.D. from the University of Pennsylvania in May 2022.

Her research agenda is situated at the nexus of ethnicity, nationalism, and migration studies. She is focused on understanding conflict processes by examining the causes of, and constraints on, government policies of group-based ethnic violence and exclusion. Garrity's book project, "Disorderly and Inhumane: Explaining Government-Sponsored Mass Expulsion," explains why and how governments expel ethnic groups en masse. Her novel Government-Sponsored Mass Expulsion dataset, published in the Journal of Peace Research, documents 139 mass expulsion events from 1900–2020, affecting over 30 million citizens and non-citizens across the world.

Garrity has over ten years of experience as a humanitarian and development practitioner throughout sub-Saharan Africa and the Middle East, and she continues to engage in annual consultancies
