I am a PhD student in Economics at CREST (Institut Polytechnique de Paris), advised by Geoffrey Barrows and Florian Grosset-Touba.

My research lies at the intersection of international trade and environmental economics. I study how the effects of heterogeneous changes in climate propagate through trade and transportation networks and redistribute losses across regions, with a focus on maritime shipping. I combine reduced-form and structural approaches: reduced-form evidence tells me which mechanisms to model, while structural models clarify what reduced-form estimates identify when regions are linked by spillovers.

In Spring 2026, I visited the Department of Agricultural & Resource Economics at UC Berkeley, hosted by Thibault Fally.

I am currently visiting Dartmouth as a Globalization Ph.D. Fellow during Fall 2026 🍂


I am on the 2026-2027 job market!
