I am an environmental soil scientist whose main research focus is understanding the impacts of human activities on Antarctic terrestrial environments. I have conducted research in Alaska, the Tibetan Plateau, Vanuatu, PNG, and the Chatham Islands. I've had 10 trips to Antarctica: including two for my PhD on human impacts on the soil environment, one to the Antarctic Peninsula as a field assistant with the Spanish Antarctic Programme, two downloading a network of soil climate stations, one installation a new soil climate station, and my first trip, to run a marathon on the continent.
I am currently involved in a multidisciplinary project characterising the environment around Scott Base, Antarctica, as a baseline against which any environmental effects of base redevelopment can be measured. I have been awarded a Marsden fast start to investigate whether penguin mounds serve as natural archives of anthropogenic contamination in remote Antarctic environments.
When not working, I like to travel, and spend a lot of time outside, cycling, hiking, scuba-diving, and fishing.
As a senior lecturer I contribute to a number of Soil and Environmental Science papers including: Introduction to Earth System Sciences (EARTH101), Environmental Monitoring (ENVSC201), Land and Evaluation (EARTH502), and I am the course coordinator for both Soil Science (EARTH221) and Soil and Water Management (EARTH322).
Soil and environmental science, especially impacts of human activities on the Antarctic terrestrial environment, local and regional scale impacts and rates of soil recovery. These interests expand to both native and arable land systems in New Zealand, and in particular how land use change impacts soil quality, soil health and soil contamination.
Pedology, Antarctic soils and environmental impacts.
