Junjie Zhang is an Associate Professor in the School of Global Policy and Strategy at the University of California, San Diego. His research endeavors to seek empirical evidence for the better design of policies on air pollution, climate change, and natural resources. He is particularly interested in using an interdisciplinary approach to attack the complex sustainability problem. Specifically, he develops economic models to answer the real-world environmental policy questions with a focus on incorporating micro behavior into environmental management. He also uses emerging data and information--including big data and satellite imagery--to study the empirical issues in environmental economics. Junjie Zhang completed his PhD in environmental and resource economics at Duke University in 2008. He also holds a BA in environmental economics and management from Renmin University of China, a BS and a MS in environmental engineering from Tsinghua University.
