View Curriculum Vitae

An Assistant Professor of Social Sciences (Environmental Studies) at Yale-NUS College, Angel Hsu is Founder and Director of the Data-Driven Environmental Policy Lab (Data-Driven Lab), a multidisciplinary research team of policy researchers, data scientists, programmers, and visual communicators. Her research explores the intersection of science and policy and the use of data-driven approaches to understand environmental sustainability, particularly in the areas of climate change and energy, urbanisation and air quality. Her research projects apply large-scale datasets derived from satellite remote sensing and other spatially-explicit sources to evaluate environmental policy performance.

Focusing particularly on China and the Global South, Asst Prof Hsu has provided expert testimony to the US-China Economic Security and Review Commission and is a member of the National Committee on US-China Relations and a Public Intellectual Program Fellow. In addition to publishing in academic journals, Asst Prof Hsu has been committed to public outreach and was a TED 2018 Age of Amazement Speaker and recognised as an inaugural Grist 50 leader. She previously held a joint appointment as Assistant Professor of Environmental Studies at Yale-NUS College in Singapore and the Yale School of the Environment as an adjunct. She holds a PhD in Environmental Policy from Yale University, an MPhil in Environmental Policy from the University of Cambridge, and a BS in Biology and BA in Political Science from Wake Forest University in Winston-Salem, NC.
