Research Interests

My research interests fall into the general areas of visual computing. I'm particularly interested in the problems which require geometric analysis and computation. I have applied geometric approaches to a wide spectrum of engineering fields, including computer graphics, computer-aided design, multimedia, wireless networking, and medical imaging. I lead the Geometric Modeling and Processing group. See http://gmp.sce.ntu.edu.sg for details.
