About me

I'm a lecturer in the School of Mathematics at Monash University, Melbourne - Australia. I'm the early career representative for the school, and open day organiser. My research interest is the interplay between algebra and combinatorics, particularly the emerging area of algebraic design theory. My current research focuses on the construction and classification of cocyclic Hadamard matrices and other orthogonal designs.


Areas of mathematics I'm interested in: algebra, algebraic design theory, category theory, combinatorial design theory, difference sets and relative difference sets, group cohomology, group theory, Hadamard matrices, orthogonal designs, representation theory of finite groups, sequences and arrays with good autocorrelation.


I'm the chief examiner, coordinator, and lecturer for Foundation Mathematics for Engineering ENG1090. I'm also regularly involved in the coordination and tutoring of ENG1005/2005, and lecturing and tutoring of MAT1841.
