I am a PhD student in the MIT Theory Group, where I am advised by Erik D. Demaine. I got my B.S. in CS/Math and MEng in Computer Science from MIT.

My research interests include graph algorithms, approximation algorithms, cache-efficient algorithms, hardness of approximation, data structures and more.
