I came to Ann Arbor, Michigan in August 2000. Prior to that I was a graduate student at the ECE Department , the Institute for Systems Research , and the Center for Satellite and Hybrid Communication Networks at the University of Maryland, College Park. Currently I am an associate professor with the EECS Department, University Michigan. I am also an affiliate member of the Center for Wireless Communications Research and the NSF Wireless Integrated Microsystems (WIMS) ERC. My research focuses on performance analysis and building energy-efficient/high-performance networking mechanisms for wireless sensor networks, mobile wireless ad hoc networks, and broadband satellite networks. I am also interested in optimal resource allocation as well as network modeling and simulation techniques for such networks.
