My main research interest is in computational topology and geometry. I work on the underlying mathematics, algorithms, and applications to scientific problems.
A link to diamorse: a code package for topological data analysis of digital images. Diamorse will compute a discrete Morse vector field, topologically dual skeletons and partitions, and persistent homology from 2D and 3D greyscale image data.
Take a look at EPINET: a web database of periodic network structures.
The hyperbolic crystallography of the cubic genus-3 triply periodic minimal periodic surfaces is here.
My PhD thesis (2000) explored the mathematical foundations for computing topological information from data.
I'm an editor for the Journal of Applied and Computational Topology.
I'm actively seeking outstanding Honours, Masters and PhD students to conduct projects in applied geometry and topology. See the Available projects tab and contact me for further details.
I supervise a few undergraduate research projects each year. Recent examples include "Investigating the relationship between curvature and deflection of thin sheets", "Symmetries of graphs on surfaces", "Polyhedral models of periodic minimal surfaces" with advanced studies students from Physics, Mathematics, and Engineering.
My past lecturing at ANU has included the Linear Algebra half of MATH1115, the basics of crystallography and thermal properties of lattices for PHYS3032 and a reading course on Applied Topology for MATH4349.

ARC Future Fellow 2014-2019 Topological data analysis for enhanced modelling of the physical properties of complex micro-structured materials.
I've worked with five artists in residence from the ANU School of Art under the ANU Vice-Chancellor's College Artist Fellowship scheme: Erica Seccombe, Julie Brooke, Al Munroe, Susan Buret, Alex Gillespie.
Erica and I published an essay "3D X-ray art" about the techniques used in her work in the Australian Physics magazine, Jan 2015.
