Alexander Kustov is associate professor of migration in the Keough School of Global Affairs and a core faculty affiliate of the Keough School's Klau Institute for Civil and Human Rights. He has been a Kellogg faculty fellow since 2026.

Kustov is the author of the Popular by Design newsletter, where he writes about immigration policy solutions that make immigration more politically sustainable.
