I'm an assistant professor from the College of Economics at Shenzhen University. I obtained my Ph.D. in economic geography from the Hebrew University of Jerusalem in 2021. I am interested in new statistical methods in spatiotemporal data. My work addresses three broad questions: (i) How do idiosyncratic shocks propagate in different economic entities such as cities, firms, etc. (ii) how do urbanization and migration shape commuting and residential behavior in megacities and (iii) what are trade frictions on industrial and firm-level.

​

These research areas present a causal inference challenge, as spatial spillovers and interactive effects usually exist when a policy or experiment has been implemented. I draw on natural experiments from geography, history, and policy and use econometric and statistical techniques to advance our understanding of spatiotemporal interactions.
