I am a Marine Geophysicist specialising in Arctic/Antarctic ice-sheet history, glacial geomorphology and glacial/glacial-marine processes. Specifically, I use seafloor DEMs and sub-surface profiles of seafloor sediment layers, often coupled to sediment core records, to reconstruct past ice-sheet behaviour and changing environmental conditions during deglaciation from the last ice age and during Holocene natural variability. I have also worked with remote-sensing data and I enjoy forging links between different disciplines be they observational or more theoretical. My technical specialisms include the acquisition, processing and interpretation of multibeam swath bathymetry, sub-bottom profiler records and shallow marine sediment cores.
