Communications and Information Theory
Our department hosts a world-class research group in Communications and Information Theory and is the birth-place of the field of Network Coding.
This research area covers a wide range of topics in information theory, channel coding theory, switching theory, and performance analysis. Our research deals with the fundamental aspects of information and uses mathematical tools to obtain the limits of data compression, channel coding, network performance, etc. We also design efficient algorithms for related applications.

Networking Theory, Internet and Applications
Our department is especially strong in networking research that covers a broad scope from software used to control network activities to hardware for transporting data over wired and wireless channels. We also do research in incentive mechanisms for networks by applying ideas from game theory and economics.
The research on Internet technologies and applications includes three main areas:
- Infrastructure-related issues - broadband technologies, next generation Internet protocols, intelligent routing, quality-of service control, broadcasting and multicasting, multimedia streaming, distributed content caching and routing, intelligent content adaptation.
- Internet Security - cryptography, authentication, digital watermarking, secured application protocols, etc.
- Internet applications - intelligent bilingual search engines, multiparty video conferencing systems, multimedia streaming systems, Internet for learning systems, etc.

Multimedia Processing
The explosive growth of multimedia information over the Internet makes it an urgent task to develop intelligent systems for automatic multimedia processing. Our multimedia research focuses on intelligent processing of image, video, and computer graphics. Current topics range from image and video indexing and retrieval, image and video based biometrics, video based character recognition, to 3D graphics.

Optical Communications
Optical fiber is the dominant medium for long distance high-capacity transmission systems. Our major thrust in lightwave network research is to identify system/ network architectures and the supporting technologies that allow the sharing of the enormous bandwidth available in the optical fiber.
