I'm an environmental geochemist working across the land-water continuum.
Research in my group (Waikato Environmental Geochemistry (WEG)) spans systems (soils, caves, groundwater, lakes, rivers and coasts) and topic areas, employing a range of geochemical techniques in combination with interdisciplinary approaches.
Our interdisciplinary approach lends itself to innovation. WEG research has produced several new technical solutions to improve environmental sampling and laboratory experimentation. For example, with the SYP autosampler, we have developed the first, robust and fully automated water sampler for cave environments. The Geological Microclimate system (GeoMic): a climate controlled box for geochemical experiments, was developed by our group for precise experiments examining mineral formation and dissolution processes.
While much of our research is Waikato and NZ-based, our cave research takes us to diverse environments from the Southern Alps to the tropical Pacific. Waikato's unique location in the southern mid-latitudes provides the opportunity to understand key parts of the global climate system, such as the Southern Hemisphere Westerly Winds and El Niño–Southern Oscillation (ENSO).
I welcome enquiries from motivated students with backgrounds in chemistry, biosciences, Earth sciences or engineering.

Understanding environmental nanoparticles
My research focuses on the interaction between environmental nanoparticles and trace elements in soil, water and minerals.
Dissolved organic ligands and colloids are key controls on trace elements in most aquatic settings. For example, we are studying the controls on metal incorporation into cave minerals, or the regulation of nutrient bioavailability by iron nanoparticles.
Minerals as environmental and climatic archives
Minerals, such as this stalagmite (left), are fascinating because they conserve information about their environments of formation through trace elements, isotopes and by sequestering organic molecules from their surroundings. These natural archives can allow us to address all sorts of interesting questions about the Earth, both in modern systems and ancient palaeoclimates.

WEG researchers combine techniques from geochemistry and environmental chemistry, such as DGT, for the tracking of environmental contaminants (right). We are actively developing tools for the monitoring of pollutants in soil and water, as well as optimising mitigation technologies to reduce the impact of agriculture on freshwater ecosystems.
Isotope ratios are a key tool in geoscience. Our research group applies isotopes to enrich our understanding of processes, identify sources and un-mix inputs in different systems and settings. For example, our research on cadmium (Cd) isotope ratios in agricultural systems has provided an improved understanding on Cd leaching rates. Similarly to isotopes, organic fluorescence is a complementary method to rapidly screen organic inputs in water, e.g. sewage derived inputs to aquifers. Fluorescence is widely applicable, for example, in elucidating the trophic status of lakes through time, or in identifying aerosol deposition in Antarctic ice (an ongoing collaboration with researchers at the Antarctic Research Centre).
