More information about my research can be found at the Networking and Information Processing Laboratory (NetIP), where I'm the Co-director.
My research interests are in the areas of Digital Signal Processing and Wireless Communications and Networking. As such, my past and current work focuses on problems and topics that are at the intersection of these two areas. The main topics of my research are multimedia wireless communications, user cooperative communications, cognitive radio, multiple access to wireless networks, cross layer designs (especially joint source-channel coding and resource allocation), Digital Signal Processing algorithms and architectures, and speech and video processing for wireless communications.
