Welcome to my page! 

My research focuses on International Trade and Industrial Organization, with an emphasis on firm decisions in trade and innovation and how they interact with policies.

I am an Assistant Professor in the Department of Economist at Penn, where I joined in July 2025. Prior to joining Penn, I was an IES Postdoctoral Fellow at Princeton University during the 2024–2025 academic year. I received my Ph.D. in Economics from NYU in 2024.
