About Adam

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.

Research Interests

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.

Isotope systematics

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
• Ultrafiltration
• Inductively coupled plasma mass spectrometry (ICPMS), including laser-ablation (LA-ICPMS)
• Stable isotope mass spectrometry (IRMS and CRDS)
