I am currently a postdoc in the Computer Science and Mathematics departments at MIT, where I collaborate closely with Ankur Moitra, Sam Hopkins and Piotr Indyk. I am broadly interested in Theoretical Computer Science and my current research interests are robust algorithm design, the sumofsquares convex programming hierarchy, randomized numerical linear algebra and high dimensional probability.
I recently finished my PhD at Carnegie Mellon University, where I was extremely fortunate to be coadvised by Pravesh Kothari and David Woodruff. During the summer of 2021, I interned with Madhur Tulsiani and Yury Makarychev at Toyota Technological InstituteChicago and in summer 2020, I interned with Ken Clarkson at IBM Almaden.
Even earlier, I was an undergrad at Rutgers, New Brunswick, where I had the pleasure of working with Martin FarachColton
and Pranjal Awasthi.
