I am a professor of economics at Clark University, specializing in urban and regional economics. My research interests include urbanization in China, regional development, entrepreneurship and job creation, high-tech industrial clusters, and racial housing segregation. I received a B.A. from Renmin University of China and a Ph.D. from Johns Hopkins University, both in economics. I was a dissertation fellow at the Brookings Institution during 2000-2001. Before joining Clark University in 2006, I worked as a research fellow at the Public Policy Institute of California. I have been an IZA research fellow since 2007.
