I work at the Gippsland Campus of Federation University of Australia as a lecturer in mathematics and statistics.

My research interests include algebraic topology and mathematical modelling.

My interest in algebraic topology centres on the algebraic structure of integral cohomology groups together with all primary n-ary cohomology operations, stable and unstable. In particular, the Eckmann-Hilton duality of these ``H(R)-algebras'' and the ∏-algebras of homotopy theory, generating sets of integral cohomology operations, relations between these operations and the distinction between integral cohomology operations and those over field coefficients. I am also interested in the use of spectral sequences and aspects of category theory.

I am interested in collaboration across disciplines and indeed this has been my main focus in recent years, with more opportunity for publication. I find this research rewarding because the applications are usually of a less theoretical nature than algebraic topology, though these applications have still been at the forefront of genetics, microbiology and engineering. Currently I research 4 wheel drive/4 wheel steer vehicles and the modelling of CO2 capture from flue gas of coal fired power plants.

Future research supervision

Andrew will supervise honours, masters and PhD students in the mathematical modelling areas of robotics and automation, carbon capture from coal fired power plants or on any suitable project suggested by a prospective student. For students with a strong background in algebraic topology he will also supervise projects on spectral sequences and integral cohomology operations.
