Institut des Hautes Études Scientifiques

Hugo Duminil-Copin is a French mathematician and permanent professor at the Institut des Hautes Études Scientifiques (IHÉS) near Paris, with a concurrent professorship at the University of Geneva. He works at the interface of probability theory and statistical physics, where he has become the world's leading authority on the rigorous mathematics of phase transitions and lattice models such as percolation, the Ising model, and the random-cluster (FK) model. His results settled foundational questions about continuity of phase transitions, sharp thresholds, and conformal invariance in two-dimensional systems, translating heuristic ideas from physics into theorems. For this work he received the Fields Medal in 2022, having earlier won the EMS Prize, the New Horizons in Mathematics Prize, and the Loève Prize. His research is purely theoretical, with no patents or commercial affiliations. As an outreach anchor he represents the probability and statistical-physics community — audiences relevant to scientific-computing platforms, Monte Carlo simulation tooling, and high-performance numerical research environments used across academic physics and mathematics departments.
