Research Expertise and Interest
information theory, communications theory, wireless communication, cognitive radio, distributed control, spectrum sensing, spectrum sharing, spectrum policy, power consumption in communications systems

<p>My areas of interest are communications, control, and signal processing. On the communications side, my interests are particularly in the areas of wireless and information theory. Within information theory, one of my current areas of interest is in developing conceptual tools needed to understand the fundamentals of "quality of service" beyond classical Shannon data rate. On the "quality of service" side, I have a particular interest in both delay and power consumption. To that end, I am interested in distributed control systems as they provide well formed mathematical models that do not mesh with the classical notions from information theory. In addition, distributed control is a setting in which we can explore the role of implicit communication/signalling.</p> <p>I am also interested in how multi-scale heterogenous wireless systems can coexist peacefully within the context of cognitive radios. This is the general problem of spectrum sharing. Besides being an interesting case of distributed control, this brings legal and economic concerns together with communications and signal-processing in a non-trivial way.</p>
