Meet our Visitors for 2017-2018 Academic Year

The Inaugural Perry World House Visiting Fellows and Visiting Scholars hold expertise in areas critical to Perry World House’s two inaugural research themes: The Future of the Global Order: Power, Technology and Governance and Global Shifts: Urbanization, Migration and Demography. Fellows will examine how power, technology and governance interact in a new global order and how urbanization, migration and demography are shifting the ways we govern and live. Visitors bring valuable expertise across a range of issues, including U.S. foreign policy, military technology and counterterrorism, international economic policy, global urbanization, E.U. foreign policy, China-U.S. relations, refugees and migration, humanitarian intervention, technology and warfare and global security.

Perry World House is Penn’s new hub for global engagement and international policy research. Bringing together students and faculty from across Penn’s schools and disciplines with practitioners and policymakers from around the world, it convenes conversations around the most pressing global challenges, catalyzes interdisciplinary academic research with policy relevant potential, and connects Penn to the world and the world to Penn.
