I'm an environmental economist and an assistant professor at the Department of Economics, National University of Singapore. 

My research examines how environmental stressors and regulations affect local socioeconomic outcomes, as well as nonlocal outcomes through trade linkages, air or ocean flow, social media networks, and transportation infrastructure. I also study greenwashing efforts and methane leakage from fossil fuel operations.

I received my Ph.D. from the Sustainable Development program at Columbia University in 2023.
