Personal profile
Biography
I work in the NERC Centre for Polar Observation and Modelling (CPOM). My research focuses on using satellite and airborne altimetry data over the Greenland and Antarctic ice sheets to detect and interpret changes in their elevation, volume, and mass and estimate their contribution to sea level rise.
Education/Academic qualification
PhD, Improving estimates of ice sheet elevation changes from AltiKa and CryoSat-2 satellite radar altimetry, University of Leeds
