Gordon''s research involves the representation theory of groups. He is particularly interested in symmetric groups and general linear groups and the combinatorics associated with them. A series of his papers have been concerned with evaluating decomposition numbers of various groups and establishing patterns in the decomposition matrices. 
Gordon also studies q-analogues of the symmetric group algebra, especially Hecke algebras and q-Schur algebras. A collection of fundamental papers has established the relationship between repesentations of general linear groups in both the describing and non-describing characteristic cases and repesentations of symmetric groups. The main key in this area is the q-Schur algebra, which was introduced by Gordon and R. Dipper.
