Justin K. Canfil is a Stanton Nuclear Security Fellow at the Council on Foreign Relations (CFR), on leave from his position as an assistant professor at Carnegie Mellon University. A political scientist by training, Dr. Canfil's research broadly concerns the impact of emerging technologies on international law, arms control, and international security. While at CFR, he is completing a book manuscript that explains how arms controllers engineer against technological creativity, and why these efforts succeed or fail.

Dr. Canfil has held postdoctoral fellowships at the Belfer Center for Science and International Affairs at the Harvard Kennedy School, Princeton's Center on Contemporary China, and the Columbia-Harvard China and the World Program. He also received a Fulbright Scholarship to China in 2019. He holds a PhD from Columbia University, with a minor in international law from Columbia Law School.
