Dr Matthew Fayers
Reader in Pure Mathematics
School of Mathematical Sciences
Queen Mary University of London
Research
Representation theory, Algebraic combinatorics, Finite groups, Hecke algebras, Quantum algebra
Interests
My research interests are in algebra and combinatorics, stemming mainly from the representation theory of the symmetric group in prime characteristic, and the associated combinatorics of integer partitions. Beyond the symmetric group, I study Iwahori-Hecke algebras and quantum Lie theory.
