My research expertise is in the field of glaciology, specifically glacier mass balance, dynamics, and climate change, with a focus on mountain glaciers in the New Zealand Southern Alps. I am very interested in glaciological change that occurs over short temporal scales; that which impacts utilization of the glacier resource, for example glacier-tourism. I also focus on interactions and feedbacks between all aspects of glacier mass balance from snow accumulation processes to ablation processes, including the role of avalanche nourishment to glacier resilience. Most recently, I have been exploring rapid change at lake-calving glaciers.For further information about my current research projects check out the following links....Climate change and rockfall on glaciers: implications for glacier tourismhttp://www.geog.canterbury.ac.nz/research/staff/climate_change.shtmlBathymetric and terminus evolution at Tasman Glacierhttp://www.geog.canterbury.ac.nz/research/staff/tasman.shtml
