Welcome! I am an Assistant Professor in the Department of Political Science at Villanova University. I study how the organization of global production reshapes the politics of trade, money, and economic security.

My book, The Exporters' Paradox: How Global Production Reshaped the Politics of Exchange Rates (under submission), explains why currency manipulation, for two decades a defining conflict of international economic diplomacy, receded without a treaty, a sanction, or an enforcement mechanism. When exporters assemble their goods from imported components, a weaker currency raises their costs as much as it helps their sales, and the domestic coalition for undervaluation comes apart. The book traces this mechanism using firm-level survey data and interviews with firms, business federations, and central bankers in Czechia, Japan, South Korea, and Taiwan.

A second line of research asks what happens as tariffs and geopolitical risk pull production chains back together. A Cambridge University Press Elements book, under contract, explains why only some governments commit public funds to reshoring strategic production. Related work examines whether control over critical minerals and green supply chains can be converted into currency power.

I am also building an open database of global value chains, covering 85 countries from 1995 to 2025, to support research on the countries that proprietary data sources leave out.

I received my Ph.D. in Political Science from the University of California, Los Angeles, M.Sc. in Economics and Management Science from Humboldt-Universität zu Berlin, M.A. in Politics from New York University, and B.A. in Political Science from DePaul University. I have held research appointments at the World Trade Organization, Washington University in St. Louis, and the Niehaus Center for Globalization and Governance at Princeton University.
