## Brief Bio

I received my PhD from UT Austin advised by Adam Klivans, where I was partially supported by the Simons Award for Graduate Students in Theoretical Computer Science, and Bachelor's degree from IIT Kanpur advised by Surender Baswana.

I will join the Computer Science Department (and the diverse theory group) at CMU in Fall 2019.

## Research

I am broadly interested in theoretical computer science.
My recent research has focused on investigating *meta-algorithms* such as the Sum of Squares method and Extended Formulations. Specifically, I have worked on

1) obtaining **fast algorithms** for problems arising in *unsupervised machine learning*, *combinatorial optimization*, *quantum information* and *cryptography* and, on the flip side,

2) obtaining general lower-bound techniques to gather evidence for tight **computational vs statistical complexity trade-offs** for some basic problems arising in average-case complexity.
