Biography

I work in the domain of smart phone based sensing systems. Modern mobile phones are equipped with many sensors like accelerometer, camera, GPS, microphone etc. and they can be used to capture various details about users automatically like accelerometer can be used to infer activity, Bluetooth to detect colocation, GPS to infer location, microphone to infer speech/noise. Mobile phone based sensing systems find applications in many domains such as social psychology, health care, and navigation systems. However, since mobile phones are battery-powered, continuous sensing from the sensors leads to faster depletion of the phone battery. My research is on energy efficiency of the smart phone based sensing systems.
