Biography

Prof. Dongyan Xu received her B.Eng., M.Eng., and D.Eng. degrees from the Department of Engineering Mechanics at Tsinghua University in 1998, 2004, and 2004, respectively. She received her Ph.D. degree from the Department of Mechanical Engineering at Vanderbilt University in 2008. After that, she worked as a Postdoc Fellow in the Department of Mechanical Engineering at the University of California, Berkeley for two years. She joined the Department of Mechanical and Automation Engineering, the Chinese University of Hong Kong, in 2010, where she currently is an Assistant Professor. Her research interests include thermoelectrics, thermal management, nanoscale heat transfer, energy conversion and storage, and micro/nanofluidics.
