On Twin Prime Power Hadamard matrices, with Richard Stafford, Cryptography and Communications - Discrete Structures, Boolean Functions and Sequences, 2, 2, pp. 261-269. (2010)
Difference sets and doubly transitive actions on Hadamard matrices II, this paper contains the analysis of the affine doubly transitive groups, completing the classification of difference sets arising from doubly transitive group actions on Hadamard matrices.
Classification of Hadamard matrices of order 4p, (joint with Jason Hill), this paper will contain a classification of the cocyclic Hadamard matrices of order 4p for prime p <25.
As for the talks, the information presented in these posters is likely to be out of date.
