I am a final year PhD candidate at UT Austin since 2011. I am visiting Harvard University in Spring/Summer 2016 and and located in MD 138.
My adviser is Adam Klivans .
Starting 2015, I am partially supported by the
Simons Award for Graduate Students in Theoretical Computer Science.
Earlier, I graduated from IIT Kanpur advised by Surender Baswana .

Research
I am interested in computational complexity, especially in understanding the strength of generic algorithmic schemes based on linear and semidefinite programming. I am also interested in pseudorandomness and learning theory.
