I am a professor in the ECE department at Texas A&M University. My research interests are generally in the areas of communication theory, channel coding, information theory and signal processing. Specifically, I am interested in codes on graphs, iterative decoding, joint source and channel coding, the interplay between coding and queueing and joint physical layer and network layer design. I am particularly interested in applications to wireless communications and data storage.
Research My current (as of January 2013) research projects revolve around understanding the role of structured codes in multi-terminal information theory, joint source and channel coding for wireless communications, design and analysis of codes and decoders for applications in wireless communications, data storage and optical communications, information forwarding in wireless networks, design of message passing algorithms for solving Lagrangian dynamics problems. Specific areas include the design of lattice codes, spatially coupled LDPC codes and graph-based codes with high throughput decoder architectures. Our research group's web page will give detailed information about my research interests, sponsors, students, collaborators, publications, preprints and recent presentations.

Teaching - I am teaching a graduate level course on information theory during the spring semester. During the last few years, I was involved in developing a precalculus course for freshman which involves using engineering examples for teaching mathematical concepts at the freshman level. In the past, I have taught graduate and undergraduate level courses on digital communications, signals and sysems, both basic and advanced channel coding, information theory and wireless communications.
Service - I served as the area editor for the coding theory and applications area of the IEEE transactions on communications until 2012 and I was one of the Technical program chairs for the 2010 IEEE International Symposium on Information Theory (ISIT 2010)that was recently held in Austin, Texas. I have served on the editorial board of the IEEE transactions on wireless communications and the IEEE communications letters. I have been on the technical program committee for several conferences in the past.
