I am a Senior Research Fellow in the School of Geographical Sciences, University of Bristol, and am funded by the RCUK (Research Councils UK).
My research interests are broad, but a particular focus is on icesheet-climate interactions, both in the past and in the future.
Other research focuses on understanding aspects of the palaeo record. The analysis and interpretation of palaeo data has led to the formation of many hypotheses regarding the mechanisms affecting past climate change. Models are ideal tools to test these hypotheses. In addition, modelling can itself lead to hypotheses which are testable by the collection and interpretation of new data, and can indicate regions in which new data could usefully be collected.
As part of the Descent into the Icehouse project, I am coordinating the climate and ice sheet modelling. The idea is to use complex General Circulation Models (GCMs), coupled to state of teh art ice sheet models, models to estimate the relative controls on the expansion of ice on Antarctica during the Eocene-Oligocene transition, in particular the relative importance of CO2 vs. gateway changes.
