Part 1 My primary research area is Information Theory and its application to the design and analysis of communication systems and networks, and data processing algorithms. My goal is to enhance and expand the understanding of information systems, as well as communication systems and to design reliable and efficient transmission strategies in terms of performance criteria of interest such as spectral efficiency and information rate. My research interests include (but are not limited to): cognitive networks, distributed systems, systems that involve cooperative communication, secure communication in wireless channels, designing techniques to exploit channel state information (CSI) in such systems, analysis of channels with side information in suboptimal conditions such as: asynchronism, memory, and channel uncertainty, design and analysis of data-processing algorithms, e.g., Part 2 Information-Hiding codes, and algorithms for sequential decision such as filtering and prediction.
