Research expertise

In my role as a Statistician for the School of Medicine and Public Health at the University of Newcastle I provided statistical support to researchers from Hunter Medical Research Institute working in various areas of public health research. Major projects included: Australian Rural Mental Health Study (5 year longitudinal study), GP diagnosis of dementia, Healthy Lifestyles (smoking intervention RCT for people with severe mental disorder), and a comparison study of ageing populations in the Western Pacific Region for the World Health Organisation.

My background is in Pure Mathematics. My research explored a new connection between two different areas of pure mathematics: Dynamical Systems and Operator Algebras. There is an important connection between the study of dynamical systems called Markov shifts and the study of directed graphs. In my thesis I introduced a family of higher-rank graphs (the higher-dimensional analogues of directed graphs) that arise from 2-dimensional Markov shifts with algebraic properties. I then explored the operator algebras known as C*-algebras, which are associated to this family of graphs. In particular, the C*-algebras were shown to have nice properties following from aperiodicity of the underlying graphs.
