Mehtaab Sawhney

Mehtaab Sawhney is an American mathematician and assistant professor at Columbia University. A Clay Research Fellow, several of his results have been recognized as breakthroughs.

Education

Sawhney graduated as the valedictorian of Commack High School in 2016. He then enrolled in a computer science program at the University of Pennsylvania. A year later, he transferred to the Massachusetts Institute of Technology (MIT), where he graduated in 2020 with a bachelor's degree in mathematics and a minor in computer science. He also won the Morgan Prize. After completing a one-year master's degree at Cambridge, he returned to MIT to pursue his doctoral studies. His dissertation, titled Probabilistic and Analytic Methods in Combinatorics, was supervised by Yufei Zhao.

Research

Sawhney's research interests are "broadly within combinatorics, probability, analytic number theory, and theoretical computer science". While still in graduate school, in collaboration with James Leng and Ashwin Sah, he demonstrated a major result relating to Szemerédi's theorem. More recently, in collaboration with Ben Green, he proved that infinitely many primes are of the form $p^2+n{q}^2$ for any given $n\equiv 0$ or $n\equiv 4(\mathrm{mod}6)$, noting that "the argument could surely be modified in a straightforward manner to handle arbitrary positive definite binary quadratic forms over $\mathbb{\mathbb{Z}}$".

Personal

Sawhney grew up on Long Island, and he is a Sikh.
