Martin Hairer (Imperial College London, UK)
Austrian-British mathematician working in the field of stochastic analysis, in particular stochastic partial differential equations. He is Professor of Mathematics at Imperial College London, having previously held appointments at the University of Warwick and the Courant Institute (NYU). In 2014 he was awarded the Fields Medal. In 2020 he won the 2021 Breakthrough Prize in Mathematics. He worked on variants of Hörmander’s theorem, systematisation of the construction of Lyapunov functions for stochastic systems, development of a general theory of ergodicity for non-Markovian systems, multiscale analysis techniques, theory of homogenisation, theory of path sampling and theory of rough paths and, in 2014, on his theory of regularity structures.
