Combinatorics Research Group

Professors

Jack Graver specializes in combinatorics and graph theory, and is currently interested in rigidity theory and symmetry of infinite planar graphs.

Mark Watkins is a combinatorialist who works mainly in graph theory. He has made contributions to the study of connectivity and automorphism groups of graphs. In recent years he has been investigating their relationship to the end structure of infinite, locally finite graphs.

Postdocs

Jihyeok Choi is a Philip T. Church Postdoctoral Fellow who earned his PhD in Mathematics from Iowa State University (2011). He works on graph colorings, random graphs and complex networks.

Simon Smith is a Philip T. Church Postdoctoral Fellow who earned DPhil. in Mathematics from University of Oxford (2005). He studies permutation groups (both infinite and finite) and some of the structures upon which they act: graphs, digraphs and surfaces.
