Ying He
Associate Professor |

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 sensor networking, and medical imaging.
