Extra Information
I hold the position of Professor in Mathematics and Statistics of the University of Melbourne and am currently in the role of Deputy Dean of the Faculty of Science. Previously, I was Head of School/Department of Mathematics and Statistics between 2011-2016. I was also Director of the Melbourne Graduate School of Science/Associate Dean (Graduate Program) between 2009 and 2016. I currently hold an Australian Research Council Discovery Program grant on the Interplay of Topology and Geometry in Polymeric Critical Phenomena and am a Fellow of the Australian Mathematical Society. My area of expertise is mathematical statistical mechanics and, in particular, the area of phase transitions and critical phenomena of model polymer systems, namely lattice walk models, which lies within the discipline of mathematical physics. My work endeavours to uncover the universal geometric and topological features of long chain molecules, such as DNA, in a variety of generic conditions. The models I study arise naturally in “Discrete Mathematics and Combinatorics” and in “Stochastic Processes”. I am part of a ‘Mathematical Physics and Statistical Mechanics Group‘ working on these topics. I have several projects in the general area of the statistical mechanics of lattice polymer and vesicle models where there is scope for Master of Science and PhD projects, and some where post-doctoral collaboration would be fruitful. Please contact me if you are interested. The two main topics of interest are (1) numerical analysis, both Monte Carlo computer simulation and also exact enumeration techniques, of lattice walks, and (2) the exact solution of interacting directed walk systems.
