I am a Ph.D. student in the Department of Computer Science
at Purdue University working under the supervision of
Prof. Elena Grigorescu .
Research
I am interested in wellmotivated algorithmic problems with some algebraic flavor. My research so far has focused on near neighbor search and its variants on algebraic objects such as lattices and errorcorrecting codes.
