Biography

<p>Husband, dad to 2 great girls, science and geochemistry geek. Love (in no particular order): being outdoors, doing field work, doing multivariate statistical analysis, making sciencey maps, hanging out with my family, getting good data, my church, encouraging and teaching students, environmental and social justice, prog rock/metal, playing guitar, poetry, cycling to work, movies, coffee, . . .<br>
I studied chemistry to MSc level at The University of Canterbury in New Zealand, and eventually graduated with a PhD in Soil Chemistry from Lincoln University, New Zealand. I've worked at UWA since 1995. I now call myself and Environmental Geochemist, with expertise in the application of aquatic physical chemistry and surface chemistry to a range of fundamental and applied research problems. My main current areas of research interest and achievement are: Understanding the behaviour of trace and rare-earth elements in soils, sediments and regolith; Geochemical exploration; Acid sulfate soils<br>
