Mobile Systems Researcher
I'm Robert LiKamWa, a Ph.D. student in Dr. Lin Zhong's Efficient Computing Group at Rice University.
My research focuses on increasing the battery life of smartphones and tablets while enabling them to do wildly powerful tasks. Although our devices have a diverse set of informative sensors, the challenge is to sense and process data in a power-efficient manner. Our lab uses careful observations, innovating low-level system designs to work toward this goal.
