Research
My research interests include operating system, network, and language support for large-scale distributed systems. My current research focuses on wireless sensor networks, with an emphasis on resource management, programming abstractions, and high-level languages. My group also develops and deploys sensor networks for real-world applications including neuromotor disease rehabilitation, emergency medical care, monitoring volcanic eruptions, and urban-scale environmental monitoring.

Bio: I have been on the faculty in Computer Science at Harvard since 2003. I received my M.S. and Ph.D. degrees from UC Berkeley (1999 and 2002). Following my Ph.D. work I spent one year as a visiting researcher at Intel Research Berkeley. I received my undergraduate degree from Cornell University (1996).
