As a high school student, Stevens was a student of the Ross Program, an experience which would later lead him to found the PROMYS[1] program along with fellow Ross alumni Marjory Baruch, David Fried, and Steve Rosenberg.

Stevens’ research specialties are number theory, automorphic forms, and arithmetic geometry.

He has authored or edited several books, including an exposition on Fermat's Last Theorem as well as a textbook about arithmetic on modular curves.
