Role in the Centre

My overarching motivation in physics research is to use my skills to safeguard the community and protect the environment. To this end I explore light-matter interactions with the direct aims of realizing energy efficient photocatalysts and developing Raman and other spectroscopic sensors. My work requires a transdisciplinary approach involving physics, chemistry, forensic science and engineering to deliver successful outcomes achieved through many collaborations. Particular focus areas are: understanding the nonlinear processes that can occur under high laser intensity illumination, plasmonic enhancement of photocatalytic processes at the nanoscale, and enhancing Raman signals to detect substances of interest at distance. Of key importance is the integrity of the spectroscopic measurement and what can be inferred from it. After 8 years at the National Measurement Institute of Australia, I continue to be intrigued by the research question of separating the loss processes of optical scatter and absorption. To this end we have developed various techniques and facilities to achieve this.

Short Biography

After graduating with a PhD in Laser Physics from the ANU in 1994 I joined the CSIRO- National Measurement Lab as a research scientist developing laser based methods for precise measurement utilizing nonlinear optical spectroscopy. Through my success I was awarded fellowships to the Bureau Internationale Poids et Mesures (Paris -1996), Center for Measurement Standards (Taipei – 1998) and National Measurement Institute Japan (Tokyo -2000) and the 2001 Iizuka prize for research and then joined QUT in 2002. I have successfully led proposals for competitive funding to enable my research to a total of $4 099 000. Of this $1 300 000 was internationally competitive, $2 794 000 was nationally competitive (Cat. 1 and 2). This has enabled me to publish 67 research articles in quality refereed journals such as the Journal of the American Chemical Society (IF=14.4), ACS Nano (IF=13.7), Angewandte Chemie-International Edition (IF=12.1), Journal of Physical Chemistry Letters (IF=8.7), Green Chemistry (IF=8.6), ACS Applied Materials and Interfaces (IF=8.1), and Nanoscale (IF=7.2). Since 2009, I have published 46 papers with 39 of them in Q1 journals (85%) that have been cited 1830 times in that period. My five highest cited articles have been cited 347, 247, 168, 155 and 145 times (Google scholar). Throughout my career I have maintained strong research links with industry through consultancy and contract research. In this capacity I have worked with industry leaders – BHP, Rio Tinto, BMC, Boeing, Toyota, Holden – as well as smaller organizations like FLEW Solutions. Resulting in $217 072 through industry research funding. In 2016 I was elected by my peers to Senior Member of the Optical Society of America (OSA).
