Dr. Zhijie Chen got his Ph.D. at Department of Mathematical Sciences, Tsinghua University in July, 2013 under the supervision of Professor Wenming Zou. His doctoral thesis was selected to be published in Springer theses. Before joining YMSC, he was a post-doc researcher in Taiwan University and his mentor is Professor Chang-Shou Lin. His research interests are elliptic PDEs and Painleve equations. So far he has published 24 papers. His most important contribution is: It is the first time that he and his coauthors established the deep connection between mean field equation (in Conformal Geometry) and Painleve VI equation (in Integrable System), and so found a new research area. He has been an associate professor of YMSC since September, 2016.
