I'm an environmental geochemist with interests in the trace element and isotope geochemistry of natural and human-modified aquatic environments, specialising in nano-scale and interfacial processes.
The Waikato Environmental Geochemistry (WEG) group comprises a team of researchers working on diverse topics within the broad scope of Environmental Geoscience. Essentially, we use chemical approaches to understand the natural world and our role in it.
I am looking for new students to join the laboratory and welcome inquires.

Natural ligands and nanoparticles in soil and water play a central role in controlling the mobility and bioavailability of metals and metalloids. This research theme is focused on these environmental transfer processes and their ecological impacts.
DGT (diffusive gradients in thin films) is a passive sampling technique which can be deployed for the specific measurement of dissolved species in water. Researchers in my group employ DGT to answer a range of questions relating to the chemical form (speciation) and biogeochemical availability of metals, nutrients and contaminants in soil, sediment and water.
Caves provide unique windows into the functioning of surface ecosystems and through carbonate (speleothem) deposition, record information on a wide range of processes, including infiltration dynamics, vegetation, soil carbon storage, temperature changes and much more. We are currently focusing on the interaction of colloids (particles between 1 and 1000 nm), natural organic ligands and complexed (chemically-bound) metals, in order to develop speleothem proxies of past environmental change. This work benefits from collaborations with European research organisations through project QUEST.
Soil and sediment systems
The accumulation and transfer of metals and nutrient species within soils is controlled to a large extent by interactions at the soil-water-root interface. Students in my group are involved in studying the fate, mobility and transformation of metals, toxic compounds (e.g. Cd) and nutrients in soils and sediments in collaboration with other New Zealand research institutes.
Stable and radio isotopes are essential tools in the study of Earth and environmental science. Opportunities are available for research students to use O and C isotope measurements as well as more exotic isotopes (e.g. 114/110Cd) to explore modern and ancient processes.
Analytical techniques used in WEG research include:
- Diffusive gradients in thin films (DGT)
- Flow field-flow fractionation (Fl-FFF), size exclusion (SE), normal and reverse-phase high performace liquid chromatography (HPLC)
- Fluorescence spectroscopy (3D excitation emission matrices), total organic carbon (TOC) analysis
- Inductively coupled plasma mass spectrometry (ICPMS), including laser-ablation (LA-ICPMS)
- Stable isotope mass spectrometry (IRMS and CRDS)
