My name is Kai Xu (徐凯). I am an Assistant Professor at School of Computer Science, National University of Defense Technology (NUDT). I am serving as visiting professor at Shandong University and Shenzhen University. I earned my Ph.D in computer science in 2011 from NUDT (supervisor: Yueshan Xiong). From 2008 to 2010, I worked as a visiting PhD in the GrUVi lab of Simon Fraser University (SFU), Canada, supervised by Richard (Hao) Zhang. From 2012 to 2014, I did my postdoctoral research at VCC@SIAT, Shenzhen, working with Baoquan Chen. Here is my CV (updated on 2016-08-10).

My research interests are in the areas of computer graphics and computer vision. My recent topics of interest include data-driven shape processing and modeling, high-level shape analysis, 3D geometry-based vision and robotics, etc. You are welcomed to take a look at my publication page.
