Yu Deng, John Pardon, Jacob Tsimerman and Hong Wang have been named for the Fields Medal 2026. The International Mathematical Union (IMU) presented the prestigious mathematics award during the opening ceremony of the 2026 International Congress of Mathematicians (ICM) in Philadelphia, USA, on 23 July 2026.
The Fields Medal is often compared to “the Nobel Prize of Mathematics,” for both outstanding contributions to mathematics and the promise of future contributions. It is awarded every four years to a maximum of four mathematicians who meet the award’s age requirement.
The Fields Medallists are all from distinct regions of “modern” mathematics: partial differential equations, symplectic geometry, algebraic geometry, harmonic analysis and geometric measure theory.
Why in News?
The Fields Medal 2026 is in the news, as a group of four mathematicians—Yu Deng, John Pardon, Jacob Tsimerman and Hong Wang—have been chosen for the revered accolade.
The awards were handed out at the International Congress of Mathematicians 2026 in Philadelphia. The International Mathematical Union awarded the four mathematicians for their accomplishments in various aspects of mathematics.
The 2026 edition is especially remarkable as it is the third time the Fields Medal is bestowed on a woman in its history. Yu Deng and Hong Wang were also the first Chinese people to win the Fields Medal in the same year.

Who Won the Fields Medal 2026?
The four Fields Medalists are:
- Yu Deng
- John Pardon
- Jacob Tsimerman
- Hong Wang
1. Yu Deng
Yu Deng, a mathematician at the University, has been awarded the Fields Medal 2026 for his ground-breaking work in partial differential equations and mathematical physics.
Amongst its other accomplishments, Deng’s work was cited by the International Mathematical Union for the rigorous derivation of the Boltzmann equation from hard-sphere dynamics for rarefied gases; the derivation of wave kinetic equations from nonlinear dispersive systems; and the probabilistic approach to nonlinear Schrödinger dynamics.
His research has contributed to the development of the mathematics of visualising the behaviour of microscopic particles and its implications for descriptions of physical systems on the larger scale.
It is also of historical significance for Deng to be one of the two Chinese mathematicians awarded the Fields Medal (2026).
2. John Pardon
This Fields Medal is given in recognition of outstanding contributions in symplectic geometry and to geometry and topology to John Pardon of Stony Brook University.
He is known for his work on new virtual fundamental cycles, Fukaya categories for some manifolds and counting of holomorphic curves.
Pardon has also contributed significantly to other aspects of geometry and topology, and he has contributed to work on group action on 3-manifolds, as well as knot theory.
His work reflects modern-day research in mathematics, where subjects are all interconnected, and the aim is to resolve a complex problem.
3. Jacob Tsimerman
The Fields Medal 2026 was awarded for significant contributions to arithmetic and complex algebraic geometry to Jacob Tsimerman, from the University of Toronto.
His efforts to reformulate o-minimality as a primitive technique in arithmetic and complex algebraic geometry were acknowledged by the International Mathematical Union. He also made key contributions to the proof of important conjectures like Griffiths’ conjecture on the algebraicity of images of period maps and the André-Oort conjecture for Siegel modular varieties.
His research has contributed to the emergence of new mathematical tools to understand the deep links between geometry, arithmetic, and number theory.
4. Hong Wang
The Fields Medal is awarded to mathematicians who have made outstanding contributions to the field. It is being awarded to Hong Wang of the Institute of High Studies in Sciences at the University of Paris and the NYU mathematician at the Institut des Hautes Études Scientifiques (IHES) in France for work in harmonic analysis and geometric measure theory.
Recent applications involve the use of multiscale and decoupling methods in the local smoothing conjecture (LSC) for the planar wave equation. She has also made significant progress in the fields of Fourier restriction, Falconer distance sets, Furstenberg sets and the Kakeya problem in three dimensions.
What is the ‘Fields Medal’?
One of the most sought-after in mathematics, the Fields Medal is one of the world’s most prestigious awards in mathematics. It is an institution founded by Canadian mathematician John Charles Fields, and given by the International Mathematical Union.
As will be seen, the Fields Medal does not concentrate on lifetime achievement, but instead it is targeted at superior mathematical accomplishment and promise for future accomplishment.

Conclusion
Yu Deng, John Pardon, Jacob Tsimerman and Hong Wang are all winners of the Fields Medal for 2026, for their work on many aspects of mathematics. Their areas of research include partial differential equations, symplectic geometry, algebraic geometry, harmonic analysis and geometric measure theory.
It’s special because Hong Wang was the third woman since the founding of Xiaomi in 2005 to get the prestigious award, and Yu Deng and Hong Wang were two Chinese mathematicians given the award in the same year. The International Congress of Mathematicians was held in Philadelphia on 23 July 2026, where the awards were announced.
