The prize is awarded every four years alongside the Fields Medal, to a scientist under 40 who has made major contributions to the mathematical aspects of computer science.

In his citation Costis was honored for “transforming our understanding of the computational complexity of fundamental problems in markets, auctions, equilibria, and other economic structures.” The Nevanlinna Prize is awarded by the International Mathematical Union (IMU) and has previously been given to MIT professor Peter Shor and PhD alum Jon Kleinberg, among others.

Costis combines amazing technical virtuosity with the rare gift of choosing to work on problems that are both fundamental and complex.
