Biography

Academic Leadership

National Roles:

  • Mathematics in Industry Study Group (MISG) Director (2012 – 2015).
  • ATN Industry Doctoral Training Centre (IDTC) Node Leader (2013 – present).

State Roles:

  • Queensland Studies Authority (QSA) State review Panel Member (Mathematics C) (2007 – 2013).

Current Research Projects

  • The mathematical modelling of the production of bio-fuels from cellulosic materials. This project specifically considers the acid pretreatment and the enzymatic hydrolysis of bagasse (sugar cane fibre residue).
  • The mathematical modelling of electrochemical nano-dioides. These are nano-porous devices that rectify the passage of current in an electrolyte solution. This project considers electric double layer formation and interaction, charge transport in electrolyte solution using Poisson-Nernst-Planck and modified Poisson-Nernst-Planck models as well as discrete to continuum approaches for modelling low density flows.
  • The optimisation of metal-air batteries. This work involves a complementary experimental and mathematical modelling approach to provide decision support capabilities for the understanding and subsequent optimisation of lithium-air electrodes for secondary batteries.
  • The multiscale, mathematical modelling of periodic porous materials using a hybrid continuum/particle based approach. This projects considers the integration of microscopic scale particle based models (Smooth Particle Hydrodynamics, Lattice Boltzmann and Boundary Element) for high-dimensional Stokes flow with continuum flow (conservation of momentum and mass equations) at mesoscopic and macroscopic size scales.
  • Modelling the uptake of agrochemicals through the cuticular membranes of plant leaves. This project aims to develop novel mathematical models of chemical uptake in plants. It is envisaged that such models can then be utilised to better understand this process as well as develop more efficacious agrochemicals..
  • The Intermittent Microwave Convective (IMWC) Drying of food. This project is developing multiphase, multicomponent mathematical models of food materials that account for free and bound water transport and material deformation during drying.
  • Predicting the component gas concentrations of coal seam gas (CSG) reservoirs over time using a mathematical modelling approach. This project develops a population of models (PoMs) to predict the changing gas composition at a CSG compression facility. The individual reservoir models that feed into the PoMs are volume averaged unsaturated porous flow models that account for multicomponent liquid and gas transport within the matrix and cleat scales of individual coal seams.
  • Thermal Modelling of Large-Scale Biomass Stockpiles. This project addresses the important problem of preventing spontaneous combustion in large stockpiles of bagasse (sugar cane fibre residue). This will significantly extend its availability for renewable energy products.
  • Phase field modelling of Lithium Metal Phosphate Batteries. This project is looking at the development and numerical solution of mutliscale, high-dimensional, Cahn-Hilliard Reaction models to predict the phase change behaviour within secondary, lithium-ion batteries. Such model systems are notoriously difficult to solve accurately and novel numerical approaches have been developed to achieve this.

Teaching Paradigm

As a lecturer in the Mathematical Sciences at QUT my primary aim has been to improve the learning outcomesof those students, both undergraduate and postgraduate, who take my units, are involved in the courses that I coordinate and/or are under my supervision for research training. I have attempted to do this in a number of ways, namely:

  • By providing a stimulating and exciting environment in my lectures, tutorials and in interacting with my postgraduate students that is conducive to learning and draws upon my research experience;
  • By adhering to a reflective teaching practice in which I always seek to critically evaluate student centred data of my teaching quality;
  • By developing and implementing high-quality, innovative, flexible and relevant learning resources (that have been externally recognised by the Carrick Institute);
  • Via my involvement in the implementation of student support programs;
  • By developing, improving, coordinating and promoting postgraduate coursework and honours programs in the Mathematical Sciences.

Experience

Research Experience

My research expertise is a combination of Applied Mathematics and Physical Chemistry, specifically related to industrial systems in the area of energy technology. The key points relating to my research activities are as follows:

  • The significance of my work stems from its high degree of industrial relevancy. It has had high impact in; and been extremely well received by; the industries to which it is targeted. This is underpinned by a significant record of long-term and ongoing collaboration with industry.
  • I have a strong record of external research funding (in excess of $2.8M in external funding from 2000 to 2015) including 7 nationally competitive grants, 1 Qld State Government award and 7 industry funded grants.
  • I have a strong record of leading research teams to facilitate the successful completion of large-scale projects.
  • I have a good record of publications in high quality (Q1) academic journals.
  • I have undertaken several at-scale, commercial-in-confidence research projects for large companies.
