Update: As of September 2007, I have joined Google and am no longer affiliated with University of Wisconsin.

The following is a breakdown of my eight broad areas of past (recent) research projects.

	1. Sensor Coverage 0/1 Coverage Best- and Worst- case coverage Exposure Field-of-view sensor coverage Probabilistic mobility models and coverage
2. Experimentation Platforms 802.15.4 and Zigbee platforms Rapid prototyping Low power wireless video networks
	3. Experimental analysis and modeling Experimental studies of 802.15.4 networks Interference and jamming in 802.15.4 Power analysis and hardware power management Transmit power control in 802.15.4 and Zigbee networks Channel mangement in 802.15.4 and Zigbee networks
4. Video Surveillance Networks Multi-camera target localization Multi-camera sensor calibration for detection Obstacle estimation in camera networks Camera network image stitching and fusion Wireless Video Tracking Demo
	5. Wireless Node Localization Transmit power control and node localization Accelerometer-assisted location tracking
6. Sensor Networks Efficient data gathering Root selection for fusion Compression-centric routing Phenomena boundary tracking Sensing driven clustering
	7. Smart Spaces Distributed actuation for environment control Efficient environmental monitoring (HVAC)
8. Inter-Sensor Data Prediction Data prediction models Active Prediction
