Khot received the 2014 Rolf Nevanlinna Prize by the International Mathematical Union and received the MacArthur Fellowship in 2016. [3] He was elected a Fellow of the Royal Society in 2017 [4] and was inducted into the National Academy of Sciences in 2023. [5]

Education

Khot obtained his bachelor's degree in computer science from the Indian Institute of Technology Bombay in 1999. [6] He received his doctorate degree in computer science from Princeton University in 2003 under the supervision of Sanjeev Arora. His doctoral dissertation was titled "New Techniques for Probabilistically Checkable Proofs and Inapproximability Results." [7]

Honours and awards

In computational complexity theory, the unique games conjecture is a conjecture made by Subhash Khot in 2002. The conjecture postulates that the problem of determining the approximate value of a certain type of game, known as a unique game, has NP-hard computational complexity. It has broad applications in the theory of hardness of approximation. If the unique games conjecture is true and P ≠ NP, then for many important problems it is not only impossible to get an exact solution in polynomial time, but also impossible to get a good polynomial-time approximation. The problems for which such an inapproximability result would hold include constraint satisfaction problems, which crop up in a wide variety of disciplines.

Charles Samuel Peskin is an American mathematician known for his work in the mathematical modeling of blood flow in the heart. Such calculations are useful in the design of artificial heart valves. From this work has emerged an original computational method for fluid-structure interaction that is now called the “immersed boundary method", which allows the coupling between deformable immersed structures and fluid flows to be handled in a computationally tractable way. With his students and colleagues, Peskin also has worked on mathematical models of such systems as the inner ear, arterial pulse, blood clotting, congenital heart disease, light adaptation in the retina, control of ovulation number, control of plasmid replication, molecular dynamics, and molecular motors.
