  • Internationally recognised research leader in (a) theory and applications of probabilistic inference, including maximum entropy analysis and Bayesian inference; and (b) environmental contaminants, systems and impacts. This includes:
    • Maximum entropy analysis, Bayesian inference and machine learning applied to networked flow systems, including water distribution, energy distribution, transport and electricity distribution networks;
    • Maximum entropy analysis and Bayesian inference for the analysis of fluid flow systems, dynamical systems, dissipative systems and fluid turbulence;
    • Dimensional analysis, Lie scaling, and spatial and parametric analogues of the Reynolds transport theorem, Liouville equation, and Perron-Frobenius and Koopman operators;
    • The combinatorial basis of entropy and its applications, including to the analysis of graphs and flow networks;
    • Per-and polyfluorinated alkyl substance (PFAS) contaminants such as perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA), including entrapment mechanisms and their active remediation by in situ fluidization.
    • Non-aqueous phase liquids (NAPLs) in porous media, including surface/interfacial tension phenomena, nucleation phenomena and multiphase systems;
    • Heavy metal and inorganic contaminants in surface waters, groundwater and soil;
    • Environmental impacts, sustainability and environmental management.
  • Success in research funding, with a career total of A$3.4 million in grants and fellowships from Australian, European, French, German, Japanese, UK and U.S. sources. This includes ARC Discovery Project grants for 2010-12 and 2014-16, and an ARC SRI PFAS grant over 2019-21.
