I am an economist who studies the causes and effects of international migration, advises policy makers on new institutions can raise the benefits of migration relative to its costs, and empowers future policy innovators. I serve as a Professor of Economics and founding faculty at the School of Government & Policy, Johns Hopkins University, and a Non-Resident Senior Fellow at the Peterson Institute for International Economics. 

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, an External Research Fellow at the Centre for Research and Analysis of Migration (CReAM) at University College London and 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 served from 2023–2026 as full professor in the Dept. of Economics at George Mason University. I hold a Ph.D. from the Department of Economics at Harvard University.
