Dimitris Anastassiou is professor of electrical engineering and director
of the Columbia New Media Technology Center. He is co-director of Columbia's
Image and Advanced Television Laboratory and is conducting research in signal
processing and coding for digital video, including HDTV. His research
interests include digital video processing with emphasis on multimedia
applications. He holds masters and doctoral degrees in electrical engineering
from U.C.–Berkeley. Anastassiou joined the Columbia faculty in 1983. He holds
several U.S. patents for data compression techniques and video shading
effects.
 Alexandros Eleftheriadis is assistant professor of electrical
engineering. He holds masters and doctoral degrees in electrical engineering
from Columbia and joined the faculty in 1995. Eleftheriadis is leading a
research team working in the areas of visual information representation and
compression, video communication systems (including video-on-demand and
Internet video), distributed multimedia systems and the fundamentals of
compression. He holds four U.S. patents relating to multimedia compression
technology.
 Shih-Fu Chang is associate professor of electrical engineering. He is
co-leading the development of Columbia's multimedia testbed and audio-visual
service interoperability experiments. Chang's research interests include image
and video signal processing, multimedia information systems and content-based
visual access. He holds a Ph.D. in electrical engineering and computer science
from U.C.–Berkeley. He has conducted research at Bellcore in Morristown, N.J.,
and joined the Columbia faculty in 1993.
 Steven K. Feiner is associate professor of computer science, where he
directs the Computer Graphics and User Interfaces Laboratory. He received a
Ph.D. in computer science from Brown and joined the Columbia faculty in 1985.
His research interests include knowledge-based design of graphics, user
interfaces, virtual worlds and augmented reality, animation, visual languages,
image synthesis, hypermedia and visualization. He is the recipient of an
Office of Naval Research Young Investigator Award and is co-holder of a U.S.
patent for a multivariate data visualization technique.
 Aurel A. Lazar is chairman and professor of electrical engineering and leads the COMET research group (Control, Management and Telemedia). He holds a Ph.D. in information sciences and systems from Princeton and joined the Columbia faculty in 1980. His involvement with gigabit networking research led to the first fully operational service management system on ATM-based broadband networks. The system was implemented on AT&T's XUNET III gigabit platform spanning the continental U.S. His management and control research pioneered the application of virtual reality to the management of ATM-based broadband
networks.
 Kathleen R. McKeown is professor and department chairman of
computer science and heads the University's research effort in digital
libraries. She holds a Ph.D. in computer science from Pennsylvania and joined
the Columbia faculty in 1982. Her research interests include natural language
generation, multimedia explanation, user modeling and statistical natural
language techniques. She supervised the development of Columbia's Functional
Unification Formalism, software that can generate gramatically correct English
and has been exported to more than 60 sites worldwide.
 Shree K. Nayar is professor of computer science. He received the Ph.D. in electrical and computer engineering from the Robotics Institute at Carnegie Mellon. His primary research interests are in computational vision and robotics with emphasis on physical models for early visual processing, sensors and algorithms for shape recovery, learning and recognition of visual patterns and vision-based robot control. He holds several U.S. and international patents for inventions related to computer vision and robotics. He joined the Columbia faculty in 1991.
 Henning Schulzrinne is associate professor of computer science. His Ph.D., in electrical engineering, is from UMass–Amherst. Before coming to Columbia in 1996, Schulzrinne was a multimedia systems researcher for GMD Fokus in Berlin. He has also conducted research on packet audio tools in Israel and on network emulation and multimedia for AT&T Bell Laboratories in New Jersey. He holds a U.S. patent for a method to protect electronic publications that use cryptographic protocols.
