Paul Diefenbach
Associate Professor



URBN Center, 220F

Dr. Paul Diefenbach, Associate Professor in Drexel University’s Digital Media program, created the game design curriculum which is now ranked #7 in the nation by The Princeton Review and GamePro Magazine. He is co-founder of Drexel’s game research laboratory, the RePlay Lab, and leads projects in brain-computer interfaces, music-driven games, and serious games. He has over 20 years experience in 3D, game development, and human simulation. Prior to joining Drexel, he was CTO of OpenWorlds Inc., providing technology for NASA, Sony, Mitsubishi, and Boeing. His pioneering 1996 Ph.D. on multi-pass rendering serves as the platform for today’s modern real-time graphics. He has presented at worldwide conferences including SIGGRAPH, Eurographics, and I3D, and has been featured on the CBS Evening News. Dr. Diefenbach holds a Ph.D. in Computer Graphics/Computer Science from the University of Pennsylvania, where he previously taught interactive 3D graphics as Associate Adjunct Professor, and a B.S. degree in Computer Science from RPI.

PhD, Computer Science (Computer Graphics), University of Pennsylvania, 1996
Masters, Computer Science, University of Pennsylvania, 1991
Bachelors, Computer Science (EE Minor) Rensselaer Polytechnic Institute, 1989
