Changhe Tu    Professor

Dr., Prof., Associate Dean at School of Computer Science and Technology, Shandong University.
I got my Bachelor, Master, and Ph.D degrees in 1990, 1993 and 2003 respectively, all from Shandong University, China. From 2001.1 to 2002.10, I visited the University of Hong Kong as a Research Assistant in the Department of Computer Science.


My research interests include computer graphics, digital geometry processing and computer aided geometric design. Recently I mainly focus on 3D geometry modeling or processing from point cloud or image, and 3D printing.
