Suprovat Ghoshal
I am a joint postdoc at Northwestern University and TTIC, hosted by Konstantin and Yury Makarychev. Before this, I was a postdoc at U.Mich hosted by Euiwoong Lee. I received my Ph.D. from the Indian Institute of Science, Bangalore, where I was advised by Arnab Bhattacharyya and Siddharth Barman.
Research Interests: I am primarily interested in the theory of approximation algorithms and hardness of approximation of discrete and continuous optimization problems. Broadly, I have been exploring the approximability of CSPs with global constraints and various related graph expansion problems. My interests also span topics in error correcting codes and computational learning theory.
