Research Summary

Starting 2006, I will start a new research direction at MSRA. Here is a summary of my past research.

For the past ten years, my research interest has been on systems issues induced by or related to mobility in a computing system. In my Ph.D. thesis work, I studied scalability and heterogeneity issues in distributed systems and later applied them to mobile computing. After I graduated and joined HRL, I worked on heterogeneous wireless networks and studied various networking issues related to a particular type of mobile networks -- satellite networks. More recently, I focused on addressing ad-hoc mobility -- on building mobile ad-hoc networks, sensor networks and embedded systems efficiently, effectively, and securely.
