I was previously a Professor of Computer Science at Harvard University from 2003 to 2010. My research group at Harvard focused on operating systems, networking, and novel applications of wireless sensor networks, consisting of tiny, battery-powered devices capable of collecting data and communicating locally via a low-power wireless radio.
See my publications and talks page for a list of my papers and talks.
See my students page for more information on my students, advisees, and postdocs.
Some of our research projects included:
- Monitoring active volcanoes with sensor networks. Working with geophysicists from UNC, UNH, and the Instituto Geofísico in Ecuador, we deployed sensors at Volcáns Tunguruahua and Reventador in Ecuador, collecting infrasound and seismic measurements.
- Pixie, an operating system for resource-aware programming, a new approach to managing scarce resources in heavily constrained embedded systems.
- Mercury, a wearable sensor platform for high-resolution motion analysis.
- Using wearable sensors for measuring motor fluctuations in patients with Parkinson’s Disease, in collaboration with researchers at the Spaulding Rehabilitation Hospital.
- Wireless sensors for emergency and mass casualty response, in collaboration with researchers at JHU and Boston University.
- CitySense, an urban-scale wireless sensor testbed, consisting of wireless sensor nodes deployed across lightpoles in Cambridge, MA. In collaboration with BBN Technologies.
- Cobra, a content-based distributed RSS feed aggregator.
- IDEA, an approach to distributed energy management in a sensor network.
- MoteLab, an open wireless sensor network testbed.
- Regiment, a language and runtime for macroprogramming of sensor networks.
- Argos, a system for distributed measurement of WiFi network traffic in an urban setting.
- Flask, a functional programming language for sensor networks.
- Karma, a programming system for distributed micro-aerial vehicle swarms. This research was conducted as part of the RoboBees project.
- SORA, an approach to decentralized resource allocation in sensor networks.
- WhiteFi, a WiFi-like network system operating over UHF whitespaces, in collaboration with Microsoft Research.
Prior to Harvard, I was 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).
