Personal profile

Biography

I joined UWA as a research fellow in 2002, appointed lecturer in chemistry in 2004, and promoted to senior lecturer 2007. My research interests are in determining anthropogenic impacts, to develop practical tools for environmental impact assessment. Research projects range from laboratory based chromatographic analysis of environmental samples, field campaign measurements, to chemical simulations of the atmosphere. Study regions extend from local WA to wider Australia, Hong Kong, China and as far a field as the UK and antarctica.


I have a career record of over 60 publications and conference papers, with a total of 1044 citations. Prior to relocation to Australia I was a member of the European Union scientific steering committee on EUROTRAC-2 for the Chemical Mechanism Development group, and have since become a member of MASSANZ (Modelling and Simulation Society of Australia and New Zealand) CASANZ (Clean Air Society of Australia and New Zealand)


I undertook my degree and PhD at the University of Leeds, UK followed by research fellowships at Leeds and also the University of Melbourne in 1991. Building on the groundwork of my experimental elementary reaction kinetics PhD, understanding complex chemical kinetics, generating and measuring gas phase radicals at concentrations of 10^11 molecules cm-3 has led me to applying this knowledge in developing highly complex chemical models of the troposphere, as well as undertaking field measurements of atmospheric components, to aid in validating the model work.


I am a member of the original concept and development team of the Master Chemical Mechanism, and undertook the chemical software development and mechanism writing together with Mike Jenkin (Imperial College London), together we have written in excess of 10,000 elementary reactions appropriate to the planetary boundary layer, and made this available to the scientific community through a dedicated website.

Research

Chemistry in the biosphere - Experiments, modelling and analysis.

Much of my research involves the use of computer models to study atmospheric processes in detail. The models are constructed using a combination of detailed chemical mechanisms, measurements and emissions data. I have been instrumental in the development of a Master Chemical Mechanism (MCM) for use in these models.
