Research
My current and recent areas of research include:
- Antarctic ice-shelf hydrology, instability and break-up
- Meteorology, debris cover and surface hydrology of Himalayan glaciers
- Surface and basal hydrology of the Greenland Ice Sheet
- Semi-automated mapping of glacial landforms
- Surface characteristics and mass balance of Icelandic ice caps
- Mass balance of Svalbard glaciers
My research involves a combination of field-based geophysics (ground penetrating radar, weather stations, dye tracing, borehole investigations, surveying and GPS, seismometers); ii) airborne (lidar and optical imagery) and satellite (radar and optical imagery) remote sensing; and iii) in collaboration with others, physics-based computer modelling.
Supervision of Doctoral and Masters Students
I welcome enquiries from prospective PhD students and MPhil in Polar Studies students. Please look at my current and recent research interests, my current graduate students and the titles of my past PhD students' theses and MPhil students' dissertations, then get in touch with me with your ideas about research topics that I may be able to supervise.
I am specifically seeking applicants for PhD projects associated with the NERC Doctoral Training Partnership:
Modelling Melt, Refreezing and Flow of Water on Antarctic Ice Shelves (with Neil Arnold, Scott Polar Research Institute)
What are the atmospheric drivers of melt on George VI Ice Shelf, Antarctica? (with Amelie Kirchgaessner, British Antarctic Survey)
