Martin Hairer
The Medal of the Erwin Schròˆdinger Institute for Mathematics and Physics for the year 2022 is awarded to Martin Hairer, Professor at the Department of Mathematics of Imperial College London.
In the course of his distinguished career, Martin Hairer has made many deep contributions to mathematics, often motivated by fundamental questions arising in physics. His work is characterised by a combination of mathematical virtuosity guided by profound physical intuition. Martin Hairer's earliest research contributions deal with the non-equilibrium statistical mechanics of strongly anharmonic chains of oscillators. While Hairer subsequently made many deep and important contributions to various areas in mathematical physics, his main research focus is in the area of stochastic partial differential equations (SPDEs), which describe a wide range of phenomena ranging from turbulent flows to financial markets.
One of the highlights in Hairer's earlier work is a proof of ergodicity for the 2D stochastic Navier-Stokes equation with Jonathan Mattingly. Subsequently, Hairer introduced a theory of regularity structures that allowed him and his collaborators to solve a wide class of singular SPDEs. Hairer's work has transformed the field of SPDEs and it is inspiring the current generation of researchers in this area. Besides his numerous mathematical breakthroughs, Martin Hairer has provided extensive service to the mathematical community, e.g., as member of the advisory boards of the Hausdorff Center for Mathematics, Institute Henri Poincaré, Mathematisches Forschungsinstitut Oberwolfach, and the Institute for Theoretical Studies at the ETH. He has served as the Chair of the ICM 2022 Program Committee. Martin Hairer also stands out as a mentor for young mathematicians and he is widely admired for his generosity in sharing ideas.
