I am a software engineer at Google, where I work in the area of mobile computing, distributed systems, and networking. Prior to joining Google, I was a professor of Computer Science at Harvard University from 2003 until 2010, and a senior researcher at Intel Research, Berkeley from 2002-2003. I did my PhD in Computer Science at UC Berkeley (2002) and my bachelor's in Computer Science at Cornell University (1996). My research interests span a broad range of topics in the space of operating systems, networks, distributed systems, embedded systems, and programming languages.

Mercury: A wearable sensor platform for high-resolution motion analysis
RoboBees: An autonomous colony of robotic pollinators
WhiteFi: Networking in the UHF white spaces
Monitoring active volcanoes with wireless sensors
CitySense: An urban-scale open sensor network testbed
Macroprogramming languages and abstractions for sensor networks
CodeBlue: Sensor networks for medical care
MoteTrack - RF signature-based indoor localization
Hourglass and Stream-Based Overlay Networks - Network architectures for Internet-scale stream processing
TinyOS and NesC - OS and programming language support for sensor networks
SEDA - An architecture for well-conditioned, highly-concurrent server applications
Ninja - Infrastructure for scalable, composable Internet services
Jaguar - High performance networking and I/O for Java
