David Conlon may refer to multiple individuals, as it is not an uncommon name. However, one notable figure by that name is a mathematician known for his work in combinatorics and related areas. He has made significant contributions to various problems in mathematics, particularly in the field of Ramsey theory.

David Conlon studies extremal graph theory and Ramsey theory. His joint work with Jacob Fox, Choongbum Lee and Benny Sudakov shows that imposing a vertex order can make Ramsey problems substantially harder, even for matchings.[ref]

With Joonkyung Lee and Alexander Sidorenko, he also linked failures of a hypergraph analogue of the Sidorenko conjecture to improved extremal lower bounds. This turns a failed density inequality into information about constructions avoiding a specified hypergraph.[ref]
