I am an assistant professor in the School of Computer Science at the Georgia Institute of Technology. My research interests are in the design, analysis, and implementation of efficient algorithms. I'm involved in the Algorithms and Randomness Center and the Algorithms, Combinatorics, and Optimization program.

Prior to coming to Georgia Tech, I received my PhD in Computer Science at CMU, and was an Instructor in Applied Mathematics at MIT for two years. My thesis, Algorithm Design Using Spectral Graph Theory, won the 2012/2013 CMU SCS Dissertation Award.
