My research lies at the intersection of international trade and macroeconomics. I bring the dynamics of growth emphasized in macroeconomics into quantitative trade models, use spatial and micro data to study adjustment across places and firms, and examine how geopolitical power and fragmentation reshape trade policy, market access, and welfare.
How much of the gains from trade come from the creation of new products?
EU integration increased market access, product entry, R&D, and trade. I develop a dynamic general-equilibrium model combining Eaton–Kortum trade with Romer-style innovation to quantify static and dynamic gains from integration.

Why does trade adjust slowly after shocks?
A model of staggered sourcing decisions rationalizes the gap between short- and long-run trade elasticities. Applied to the US–China trade war, adjustment frictions substantially amplify welfare losses.

How does geopolitical power change optimal trade policy?
Cross-country evidence on military power and tariffs motivates a quantitative trade model in which geopolitical alignment, coercive power, and conflict outside options shape tariff choices.

Journal articles, book chapters, and technical work.
I have worked on policy inside government and multilateral institutions, advised senior decision-makers, contributed to trade-reform work, and written for broader audiences. Quantitative research, policy design, and public communication are part of the same professional agenda.
