I am a researcher in the Mobile Computing Research Center at Microsoft Research.
I build systems for recognizing human state, especially human behavior, based on sensor data. My focus is on statistical algorithms for recognition, but I am interested in model elicitation, rich representations of "common sense", sensor design, infrastructure design and high-performance/low-power implementations as well. I am currently looking at the question of how and why to build perception systems on mobile phones.
