He received his B.S and M.S. in Electrical Engineering from Tsinghua University in 1997 and 2000, and PhD in Computer Science from Stony Brook University in 2006, respectively. His research interests fall into the general areas of visual computing and he is particularly interested in the problems which require geometric analysis and computation. His recent work has focused on discrete geodesics, geodesic Voronoi diagrams, (bi)-harmonic B-splines, and their broad applications. For more information, please visit http://www.ntu.edu.sg/home/yhe .
