Research - My research interests are in the application of information theory, error-correction coding and signal processing for building reliable communication networks and reliable storage systems in the presence of unreliable channels, components or physical media. I am interested both in the theoretical and applied aspects of research in this area. Some of our recent research has applications in 5G wireless communications, cyber-physical systems, processing of large volumes of data, non-volatile memories and high-speed fiber optic communications. A high level description of some of my current projects is available here.
My current research projects include - (i) design of novel uncoordinated massive multiple access paradigms for 5G wireless communications and the Internet of Things and (ii) signal processing for big data - exploring connections between sparse signal recovery and coding theory. (iii) the use of structured codes (such as lattice codes) in multi-terminal information theory for applications in relaying (physical layer network coding, compute-and-forward and interference channels etc), (iv) design and analysis of spatially-coupled codes for applications in wireless communications and optical communications, (v) design of finite-length polar codes, (vi) design and analysis of product code based solutions for non-volatile memory. My research has been funded through 30 external research grants including 15 grants from the National Science Foundation. Our research group's web page will give detailed information about my research interests, sponsors, students, collaborators, publications, preprints and recent presentations. Please visit our research page.
Teaching - I will be teaching a graduate level course on coding theory during Fall 2016. In the past, I have taught graduate and undergraduate level courses on digital communications, signals and systems, both basic and advanced channel coding, information theory and wireless communications. I enjoy interacting with students both in the class room and in our research group. I have been an early adopter of the flipped style of teaching. My personal thoughts and statement about teaching can be found here.
Service - I currently serve as an Associate Editor for Coding Techniques for the IEEE Transactions on Information Theory. I have also been elected to the board of governors of the Information Theory Society to serve from 2016-2018. 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. At Texas A&M University, I served as the Director of Graduate Studies in the ECEN department from 2012-2014.
Selected Honors- I was the recipient of the 2001 National Science Foundation career award, the 2006 best paper award from the IEEE data storage technical committee within COMSOC, the Association of Former Students college level teaching award at Texas A&M University and the 2014 Professional Progress in Engineering award from the Iowa State University given to one outstanding alumnus under the age of 46 each year. I also received the Dean's excellence award from the College of Engineering and the outstanding professor in the ECE department awards in 2015. In 2016, I gave a keynote lecture at the ICC workshop on massive uncoordinated multiple access and I was one of the lecturers at the North American School on Information Theory. I was elected Fellow of the IEEE for contributions to coding theory and its applications to wireless communications and data storage.
