About Me
I am a sixth-year Ph.D. student in the Economics Department at Cornell University. I am on the 2026–2027 academic job market. I work on macroeconomics, environmental economics and firm dynamics. I obtained a BA in Economics from Cornell in 2021.
My research focuses on three areas: (1) firm dynamics with endogenous technology and overlooked dimensions of firm heterogeneity; (2) the micro and macro impact of climate change and emissions regulation; and (3) empirical and computational methods for heterogeneous-agent and spatial economics. I use micro data to answer macroeconomic questions.
