I am an economist who studies the causes and effects of international migration, and how new institutions can raise the benefits of migration relative to its costs. I serve as a full professor in the Department of Economics at George Mason University, and a Non-Resident Senior Fellow at the Peterson Institute for International Economics. In May 2026 I will join Johns Hopkins University as a full professor and founding faculty member at the new School of Government & Policy.

Until 2023, my professional home was the Center for Global Development in Washington, DC, where I remain a Distinguished Non-Resident Fellow. I am also a fellow at the IZA Institute of Labor Economics at LISER in Luxembourg, a fellow at the Centre for Research and Analysis of Migration (CReAM) at RFBerlin, and an invited member of the Research and Policy Network on the Political Economy of Migration at the Centre for Economic Policy Research in London/Paris. I hold a Ph.D. from the Department of Economics at Harvard University.
