I am currently working at IBM Research, India. Previously, I was a post-doctoral researcher at Carnegie Mellon University, Qatar and RWTH-Aachen University, Germany I completed my Ph.D. in 2007 from State University of New York, Binghamton under Nael B. Abu-Ghazaleh.


My general area of interest is in analysis, architecture and design of systems. Specifically, I have worked (and still continue to work) on various types of wireless networks, such as Cellular, Mesh, Cognitive Radio Networks and Distributed Camera Networks. I generally tend to like fundamental and practical problems that manifest in various types of systems.
