I am a Computer Science PhD student at University of Wisconsin - Madison, advised by Michael Gleicher and Mohit Gupta.
My research utilizes low-level techniques from computational imaging to improve robot perception. I am most interested in time-of-flight proximity sensors for up-close and distributed robot sensing.
