My research group is interested in the broad areas of information processing, transmission, and learning. We particularly enjoy analyzing simple models that require mathematical techniques from diverse areas to obtain insights for practical system/algorithm design.
Network Information Theory: A major focus of our work in this area is on the development of new analytical techniques for characterizing the fundamental performance limits of multiterminal networks.
Wireless Communications: Our goal is to establish architectural principles for the design of communication systems through the analysis of the relevant channel models. We are particularly interested in the scenarios where the transmitter side information and the receiver side information are not deterministically related.
Multimedia Signal Processing: We are currently designing a new predictive coding architecture based on the concept of virtual data and exploring its application to video compression and video descriptor compression. We are also interested in developing machine learning techniques for video analysis.
