Welcome to my website. 

I am a Public Finance Economist whose research combines optimal taxation theory and empirical analysis. I received my Ph.D. in Economics from the University of Michigan in 2026.

My research interests lie in Public Finance and Energy and Environmental Economics. My work examines the design and consequences of corrective taxes and subsidies, with applications to environmental policy, clean technology adoption, and health-related consumption.
