Ketan Mulmuley is a professor in the Department of Computer Science at the University of Chicago, and a sometime visiting professor at IIT Bombay.[1] He specializes in theoretical computer science, especially computational complexity theory, and in recent years has been working on "geometric complexity theory", an approach to the P versus NP problem through the techniques of algebraic geometry, with Milind Sohoni of IIT Bombay.[2] He is also known for his result with Umesh Vazirani and Vijay Vazirani that showed that "Matching is as easy as matrix inversion",[3] in a paper that introduced the isolation lemma.[4]

He earned his PhD in computer science from Carnegie Mellon University[1] in 1985 under Dana Scott, winning the 1986 ACM Doctoral Dissertation Award for his thesis Full Abstraction and Semantic Equivalence.[5] He also won a Miller fellowship at the University of California, Berkeley for 1985–1987, and a Guggenheim Foundation Fellowship for the year 1999–2000.[1]
