"In my classes, I try to make sure that students understand both the theoretical background and the practical implications of the material - and are able to make use of the material learned to build interesting and capable systems."
"I joined the Columbia faculty in the fall of 1996. I head the Internet Real-time Lab and also participate in the Comet lab. Technical interests: Internet real-time and multimedia services and protocols, modeling and analysis of computer-communication networks, operating systems, network security. My research focuses on Internet multimedia systems, i.e., the delivery of audio and video across the Internet. One application is the use of the Internet to carry telephone calls, leading to the possible replacement of the existing telephone system in the next decade or so. I try to combine system architecture, analysis and implementation in my research projects, leading to a number of research and development opportunities for undergraduates."
