Andrew Walder is the Denise O'Leary and Kent Thiry Professor in the Department of Sociology at Stanford University, where he is also a Senior Fellow in the Freeman Spogli Institute for International Studies (FSI). A political sociologist, Walder has long specialized on the sources of conflict, stability and change in communist regimes and their successor states. His current research focuses on changes in the ownership and control of large Chinese corporations and the parallel emergence of a new corporate elite with varied ties to state agencies. He also continues his research interest in Mao-era China, with a focus on the mass politics of the Cultural Revolution of 1966-1969. Walder joined the Stanford University faculty in 1997. He received his Ph.D. in Sociology at the University of Michigan in 1981 and taught at Columbia University, Harvard University and the Hong Kong University of Science and Technology.
