EVENT SUMMARY

Introduction

Extremal and probabilistic combinatorics studies how dense or sparse a combinatorial structure can be before a particular pattern emerges. It lies at the intersection of graph theory, probability, geometry, number theory, and theoretical computer science, and is one of the most active and rapidly developing areas in discrete mathematics. Over the past decade, the field has witnessed a remarkable series of breakthroughs on longstanding open problems, together with the development of powerful new techniques that continue to shape research across mathematics.

This summer school will provide an introduction to several central themes in extremal and probabilistic combinatorics through courses delivered by leading researchers in the field. The programme is aimed primarily at PhD students and early-career researchers, and will combine lectures with exercise sessions, student talks, and opportunities for informal discussion and collaboration. The topics covered will reflect both the classical foundations of the subject and some of its most exciting recent developments.

The school takes place at the Centre de Recerca Matemàtica (CRM), Bellaterra (Barcelona). One of the sessions will be held at the Institut d’Estudis Catalans, Carrer del Carme 47, Barcelona.

Matthew Jenssen

King’s College London (UK)

Matthew Jenssen is a Reader in Probability in the Department of Mathematics at King’s College London and a UKRI Future Leaders Fellow. His research lies at the interface of combinatorics, statistical physics, and theoretical computer science, with particular interests in discrete probability, probabilistic and extremal combinatorics, algorithms, and random matrix theory. Much of his work aims to understand how large-scale structures emerge in systems governed only by local interactions. He completed his PhD in Mathematics at the London School of Economics in 2017 under the supervision of Professor Jozef Skokan and Professor Julia Böttcher, where his doctoral work earned him the LSE PhD Prize for Outstanding Academic Performance. Following his PhD, Jenssen held a two-year postdoctoral position at the University of Oxford. In 2020, he joined the University of Birmingham as a Lecturer in Probability before moving to King’s College London as a Reader in January 2023.

Julian Sahasrabudhe

University of Cambridge (UK)

Julian Sahasrabudhe is a Professor of Mathematics in the Department of Pure Mathematics and Mathematical Statistics (DPMMS) at the University of Cambridge. His research interests lie in extremal and probabilistic combinatorics, along with their intersections with probability, analysis, and combinatorial number theory, with a recent focus on Ramsey theory on graphs, random polynomials, and random matrices. He earned his PhD in mathematics from the University of Memphis in 2017 under the supervision of Béla Bollobás. Following his PhD, he was a post-doc at the Instituto de Matemática Pura e Aplicada (IMPA) in Rio de Janeiro, Brazil and Junior Research Fellow at Peterhouse, University of Cambridge. He has received numerous prestigious honours and awards for his research, including the European Prize in Combinatorics (2021), the Salem Prize (2023), a European Research Council (ERC) Starting Grant (2024), the LMS Whitehead Prize (2024), the Mathematical Congress of the Americas (MCA) Prize (2025), and the Adams Prize (2026). He has been a speaker at the International Congress of Mathematicians (ICM) in Philadelphia.
