Andrew Treglown is a Professor at the School of Mathematics, having previously worked as a Research Fellow at Queen Mary, University of London and Charles University, Prague. Andrew is a member of the Combinatorics group. His research interests mainly focus on extremal and probabilistic combinatorics and well as applications of combinatorics to other areas of mathematics. In 2021 Andrew was awarded the Fulkerson Prize jointly with his collaborators Bela Csaba, Daniela Kühn, Allan Lo and Deryk Osthus.

Research activity

Andrew's research interests lie in a range of different areas. One topic his work has had a particular focus on is 'independent set' problems in the setting of graphs, posets and the integers. This work was supported by an EPSRC Fellowship (2015-2018). For example, a famous result of Green and Sapozhenko determines the number of sum-free sets in the first n natural numbers. In the 1990s, Cameron and Erdős raised the question of how many maximal sum-free sets there are in this setting. Through a graph-theoretic approach, Andrew and his co-authors (J. Balogh, H. Liu and M. Sharifzadeh) gave a solution to this important question.

Andrew also works intensively on matching and tiling problems for graphs and hypergraphs, and is currently supported by an EPSRC-funded project on this topic. In a sequence of several papers, he and his co-authors have established a number of minimum degree conditions for forcing a perfect matching in a hypergraph, as well as generalising classical tiling results to the settings of directed and ordered graphs.
