Science
School of Mathematics & Statistics

I completed my PhD in Operator Algebras under Iain Raeburn at the University of Newcastle in 2003. After a brief fixed-term lectureship at Newcastle, I moved to a permanent lecureship position at the University of Wollongong funded by an Australian Postdoctoral Fellowship in 2007. I was promoted to a professorship in 2012, served as Head of School (2018-2021) and was made a Distinguished Professor in 2023. In 2025 I moved to 黑料网大事记 to lead the newly formed Quantum Mathematics Research Cluster.

I have served on the Council of the AustMS (2015-2017), as its Vice President (2022-2023) and as its President (2025-2026). I have also served for over 10 years on the Australian Mathematical Sciences Institute's Research Committee.

I have been an associate editor of the Bulletin of the AustMS and the Journal of the AustMS since 2015, and of the Journal of Mathematical Analysis and Applications since 2019.

I am broadly interested in Quantum mathematics聽by which I mean the general theory of functional analysis, operator algebras and noncommutative geometry and their links to quantum physics and quantum information theory. More specifically, much of my research is concerned with abstract algebras and聽C*-algebras associated to:

  • combinatorial structures such as directed graphs and higher-rank graphs;
  • algebraic objects such as groups, semigroups and small categories with suitable cancellative properties;
  • generalised C*-dynamical systems as captured by聽product systems of Hilbert bimodules; and
  • topological dynamics encoded by locally compact 茅tale groupoids and Fell bundles over such objects.

One major theme of my research is the extent to which such objects explicitly encode the structural properties of the associated C*-algebras including features like ideal structure, stable finiteness and pure infiniteness, KMS-state structure and invariants such as K-theory and KK-classes. A second major theme involves seeking to go in the other direction, determining and also the amount of algebraic or C*-algebraic data that is required to reconstruct the underlying generating object. This has led to connections with聽Dixmier鈥揇ouady theory and work on deformations of C*-algebras by cohomological data. Since the advent of Renault's theorem about Cartan pairs of C*-algebras and the subsequent introduction of Steinberg algebras associated to聽茅tale groupoids, I have been pursuing a research program that investigates groupoids and related data as a unifying coordinatising framework for both abstract algebras and C*-algebras, and as, in the words of Abrams, a Rosetta stone for translating structural theorems about one of these classes of objects into the context of the other.
