Role in Centre

As a chemist, Aaron has expertise in the synthetic chemistry and spectroscopy of stable free radicals and porphyrinic materials, which informs collaborative projects within the Centre, developing novel imaging and diagnostic tools. He also investigates the self-assembly of functional molecular building blocks, guided by halogen bonding, to construct new solid-state materials and actively collaborates with Centre investigators working in this area. In his Research Infrastructure Specialist (Magnetic Resonance) role within QUT’s Central Analytical Research Facility (CARF), Aaron supports the Nuclear Magnetic Resonance (NMR) and Electron Paramagnetic Resonance (EPR) spectroscopy needs of QUT researchers and external clients as well as actively participating in collaborative NMR- and EPR-focused projects.


Aaron completed a PhD in Organic Chemistry at QUT in 2000, working on the development of novel water-soluble nitroxide radicals, and subsequently undertook postdoctoral research in porphyrazine chemistry at Imperial College London. On returning to Australia, he completed further Postdoctoral research at QUT, before moving to the University of Queensland in 2005 and establishing an independent research group developing tuneable photosensitisers, methodology for the halogen-bond mediated assembly of stable nitroxide free radicals and the nitroxide-mediated covalent assembly of complex polymer architectures. Aaron returned to QUT in 2014 in a teaching and research role, collaborating on halogen bond mediated self-assembly, and in 2019 was appointed to the position of Research Infrastructure Specialist (Magnetic Resonance) in the Central Analytical and Research Facility (CARF) within the Institute for Future Environments.
