Overview
I am a glaciologist and palaeoclimatologist interested in what past climates can tell us about future climate change and sea level rise. I'm a modeler and work with computer codes representing the ice sheets and climate system. I mostly focus on the Antarctic Ice Sheet as it’s by far the biggest unknown in future sea level projections.
I moved to Cornwall and the University of Exeter in 2021 from the University of Bristol, where I also completed my PhD. After a couple of postdoctoral positions, including one in Massachusetts, I was awarded a Royal Society University Research Fellowship.
I'm PI on the NERC-NSF project PLIOAMP ('Pliocene sea level amplitudes') and Co-I on NERC projects GEOICE ('Benchmark geological records for the response of the West Antarctic Ice Sheet to near future temperature'), TONIC ('Solving the Oligocene icehouse conundrum'), and UK-SWAIS-2C which is part of the international SWAIS-2C project ('Sensitivity of the West Antarctic Ice Sheet to 2 degrees of warming').
