Dr Angel Hsu is an Assistant Professor of Social Sciences (Environmental Studies) at Yale-NUS College and Adjunct of the Yale School of Forestry and Environmental Studies. She is Founder and Director of Data-Driven Yale, 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.

Previously, Dr Hsu was a Research Analyst at the World Resources Institute (WRI), a non-profit environmental think-tank in Washington, DC, where she developed corporate greenhouse gas accounting and reporting initiatives in developing countries, including Mexico, Brazil, India, Philippines and China, where she managed and led WRI’s efforts. She has written in and been cited by major media outlets, including The Economist, The Atlantic, and The Guardian and has provided expert testimony for the US-China Economic and Security Review Commission. She holds a PhD in Forestry and Environmental Studies 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.
