News I have been promoted to full Professor at Rice! The promotion was approved at the March meeting of Rice's Board of Trustees. Our paper on "DW-MAC: A Low Latency, Energy Efficient Demand-Wakeup MAC Protocol for Wireless Sensor Networks" has been accepted for publication at MobiHoc 2008. DW-MAC reduces delivery latency by 70% compared to S-MAC and RMAC, and uses only 50% of the energy consumed with S-MAC with adaptive listening. I have been appointed as an Advisory Professor of the School of Electronics and Information Engineering at Beijing Jiaotong University in Beijing, China. Formerly known as Northern Jiaotong University, BJTU is a national key university of China. Rice University Computer Science Program ranked Number 1 in the country, based on Chronicle of Higher Education-published 2007 study of Faculty Scholarly Productivity!

I joined the faculty at Rice in 2000, and was previously an Associate Professor in the School of Computer Science at Carnegie Mellon University, where I was a member of the faculty for eight years. Prior to 1992 when I joined the faculty at Carnegie Mellon, I was also at Rice University. From 1989 through 1992, I was a Research Scientist and Lecturer in the Department of Computer Science at Rice. Before this, I was a graduate and undergraduate student at Rice, completing my Ph.D. (1990) and M.S. (1985) degrees in Computer Science and my B.A. (1982) with a double major in Computer Science and Mathematical Sciences. As a graduate student at Rice, my advisor was Willy Zwaenepoel. As an undergraduate, I was a member of Lovett College, one of eight (now nine) residential colleges at Rice. Before that, I graduated from Spring High School (1978) in Spring, Texas, near Houston.

My current research focus is in the area of protocols for wireless and mobile networking, and I am leading the Monarch (MObile Networking ARCHitectures) research group at Rice University in this area. I founded the Monarch research group (the Monarch Project) in 1992 while on the faculty at Carnegie Mellon University and have continued it since moving to Rice. I have worked substantially on the problems of Mobile IP and different types of multihop wireless networking including mobile ad hoc networking, sensor networking, and mesh networking. Related to this research, I have been active for many years in the Internet Engineering Task Force (IETF), the principal protocol standards development organization for the Internet, primarily in the Mobile IP and Mobile Ad Hoc Networks (MANET) working groups. I am also currently the Chair of ACM SIGMOBILE, the Association for Computing Machinery's Special Interest Group on Mobility of Systems, Users, Data, and Computing.
