Daniel Cohen-Or is a Professor at the Department of Computer Science. He received a B.Sc. cum laude in both Mathematics and Computer Science (1985), an M.Sc. cum laude in Computer Science (1986) from Ben-Gurion University, and a Ph.D. from the Department of Computer Science (1991) at State University of New York at Stony Brook.

His research interests are in Computer Graphics, and including rendering and modeling techniques, client/server 3D graphics applications, compression and streaming techniques, real-time walkthroughs, visibility, point set representation, morphing and volume graphics. Click  here for a list of publications, or here for a selected list of abstracts.

He is on the editorial board of the international of several international journals, and a member of the program committees of several international conferences on visualization and computer graphics, including IEEE Visualization and EUROGRAPHICS. Between 1996-8 he served as the Chairman of the Central Israel SIGGRAPH Chapter.  Dr. Cohen-Or has a rich record of industrial collaboration. In 1992--93 he developed a real-time flythrough with Tiltan Ltd. and IBM Israel for the Israeli Air Force. During 1994--95 he worked on the development of a new parallel architecture at Terra Ltd. In 1996--1997 he has been working with MedSim Ltd. on the development of an ultrasound simulator. He is the inventor of RichFX, and Enbaya technologies.
