I am a UC President’s Postdoctoral Fellow in the Department of Agricultural and Resource Economics at the University of California, Davis.

My research is at the intersection of agricultural and environmental economics, with a focus on the distributional impacts of water scarcity and management. My work combines novel data sources – such as remote sensing, environmental models, and farm-level census data – with tools from public economics and applied microeconomics to guide the design of more effective and feasible policies.

Originally from Singapore, I hold a bachelor’s degree in Economics from the National University of Singapore and a Ph.D. in Economics & Environmental Science from the University of California, Santa Barbara, where I was advised by Tamma Carleton. Prior to my doctoral studies, I was a pre-doctoral fellow at the Global Policy Lab at the University of California, Berkeley, under the guidance of Solomon Hsiang.
