Biography

I am an Earth System modeller working on climate-ice sheet interactions during the Quaternary. I did my PhD at the University of Bristol with Prof. Paul Valdes and Prof Tony Payne on modelling the climate and ice sheets during the last deglaciation. It is during my PhD that I discovered the mechnism of Saddle Collapse which produced two major events of rapid sea level rise, the Meltwater Pulse 1a and the 8.2 kyr events, both of which are associated with abrupt climate changes.

I joined the University of Leeds in July 2013 to become an Academic Research Fellow in Earth System modelling. I currently co-leads the PMIP working group on the last deglaciation and the modelling working group of the Past Earth Network.
