Jacob Tsimerman

A recent article in Town Topics highlights a common bond between three of the four Fields Medal winners announced at the 2026 International Congress of Mathematicians: ties to IAS. Drawing on an interview with Director and Leon Levy Professor David Nirenberg, the article goes on to emphasize the unparalleled research conditions at IAS that foster this level of excellence. 

Three of the four winners of this year’s Fields Medal, often called the Nobel Prize of Mathematics, are affiliated with the Institute's School of Mathematics: Jacob Tsimerman, Ashvin B. Chhabra and Daniela Bonafede-Chhabra Member and Distinguished Visiting Professor; Hong Wang, Member (2019–21); and John Pardon, Visitor (2016–17). With these additions, IAS scholars have now won 49 of the 68 total Fields Medals awarded since 1936.

In a recent article for Be Giant, Jacob Tsimerman, Distinguished Visiting Professor in the School of Mathematics, is profiled for his groundbreaking proof of the André-Oort conjecture and his lifelong passion for puzzles. The contributions made to Tsimerman's breakthrough by Peter Sarnak and Jonathan Pila, Professor Emeritus and Member in the School, respectively, are also highlighted.

On September 22, the Institute officially began its 2025–26 academic year, bringing together scholars from around the globe to pursue a range of individual and collaborative projects. The 259 visiting scholars, representing 39 nations and more than 108 institutions, will work alongside the 26 permanent Faculty and 22 Emeriti, all of whom are leaders in their respective fields.

Robbert Dijkgraaf, who served as IAS Director and Leon Levy Professor from 2012–22, has been elected as a fellow of the Royal Society, alongside Shivaji Sondhi, Member (1998) in the School of Natural Sciences, and Jacob Tsimerman, incoming Distinguished Visiting Professor (2025–26) in the School of Mathematics.
