I am interested in the hydrology of cold environments and how the frozen land surface interacts with the atmosphere. Most of my current research focuses on making improved field measurements of seasonal snow and applying this knowledge in order to better constrain uncertainties in environmental models. Models I work with include catchment scale glacio-hydrological models, snow-forest-atmosphere components of climate models, and radiative transfer models used in microwave remote sensing of snowpacks.
I have extensive experience of making snow measurements in boreal and mid-latitude forests (e.g. Switzerland, Sweden, Finland, Rocky Mountains in Canada and USA), Arctic and sub-Arctic tundra (Alaska, USA, and Manitoba, Canada), sea ice (Canadian high-Arctic), and on Alpine and Polar glaciers (e.g. Switzerland, Svalbard). As many of these environments are rapidly responding to a warming climate, better measurement, modelling and critical evaluation of variations in seasonal snow contribute to improved projections of climate change and our understanding of cold regions hydrology.
