My research interests lie in using observations acquired by satellite-borne instruments to detect and monitor global environmental change. I work primarily on cryospheric change — on the glaciers of Greenland and the ice shelves of Antarctica. In these regions I make use of optical and microwave data to measure surface flow, surface elevation, and surface melt.

My current research, as a postdoc on the NERC funded MIDAS project, focusses on the stability of the Larsen C ice shelf on the Antarctic Peninsula. In addition to using remote sensing to observe the state of the ice shelf surface I have been involved in two fieldwork seasons to carry out geophysical investigations of the subsurface of the ice. Geophysical techniques included ground-penetrating radar and impact seismics, alongside colleagues using hot-water borehole drilling.

In addition to glaciology my research experience includes the retrieval and analysis of atmospheric aerosol concentrations from optical satellite data, and investigation of biospheric response, as measured by remotely sensed vegetation indices, to drought.

Research Groups

  • Glaciology Group

    A research group dedicated to furthering knowledge in the quantification of the past and future contribution from glaciers and ice sheets to sea-level rise; the processes driving the present rapid and dramatic changes observed in glaciers, and the instabilities inherent in glacial systems; and the record of palaeo-ice mass instabilities and the processes that drove these changes.
