Research Interests:

My research focuses primarily on the design of efficient algorithms for wireless mobile ad-hoc networks. Embedded sensors in mobile devices such as cars and smart phones present new opportunities to collect location-specific data about the environment. This data can be used for a great number of real-time applications. A major challenge is efficiently collecting, storing and sharing the data. I am interested in understanding the tradeoffs between energy consumption, network load and storage in the design of a fully distributed ad-hoc solution to this problem.
