I am a Professor at the Department of Computer Science. I received a B.Sc. cum laude in both Mathematics and Computer Science (1985), a 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.
My research interests are in Computer Graphics, Visual Computing and Geometric Modeling and including rendering and modeling techniques, Shape Analysis, Shape Creation and Editing, 3D Reconstruction, Photo Processing, compression and streaming techniques, visibility, point set representation, morphing and volume graphics. Click here for a more accurate H-index of publications.
I was on the editorial board of several international journals including CGF, IEEE TVCG, The Visual Computer and ACM TOG, and regularly serve as a member of the program committees of international conferences. Between 1996-8 I served as the Chairman of the Central Israel SIGGRAPH Chapter. I have a rich record of industrial collaboration. In 1992—93, I developed a real-time flythrough with Tiltan Ltd. and IBM Israel for the Israeli Air Force. During 1994--95 I worked on the development of a new parallel architecture at Terra Ltd. In 1996--1997 I have been working with MedSim Ltd. on the development of an ultrasound simulator. I am the inventor of RichFX, and Enbaya technologies. I was the recipient of the Eurographics Outstanding Technical Contributions award in 2005.
