About Adam

I'm an environmental geochemist, which means that I apply geochemical tools (isotopes, trace elements) to address environmental questions. Most of my research revolves around understanding how trace elements and isotopes are captured by speleothems (cave carbonates) in order to decipher the signals of past climate changes. However, I'm also keenly interested in biogeochemical cycling and soil science.

The Waikato Environmental Geochemistry (WEG) group are a team of researchers working on diverse topics within the broad scope of Environmental Geoscience. While diverse, our work is unified by our use of chemical approaches to understand the natural world, and our role in it.

Research Interests

Understanding environmental nanoparticles

I am particularly interested in the interaction of environmental nanoparticles and dissolved organic ligands with trace elements, and how these interactions affect other phenomena. For example, the role of organic ligands in controlling metal incorporation in cave minerals, or the regulation of nutrient bioavailability by iron nanoparticles.

Minerals as environmental and climatic archives

Minerals 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.

Environmental contaminants and mitigation

WEG researchers combine techniques from geochemistry and environmental chemistry for the tracking of environmental contaminants. 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.
