My current research interests are in finite group representations and in combinatorics. I am particularly interested in primitive permutation representations of almost simple groups which are multiplicity-free and have only one or two real irreducible constituents. This interest grew out of my consideration of directed graphs and their automorphism groups. I am also interested in group designs, in particular Generalised Bhaskar Rao Designs and Generalised Hadamard Matrices in various dimensions. I am a member of the Algebra research group.
My PhD was awarded in 1999 and my supervisor was Associate Professor Don Taylor. |
