Dr Lauren Gregoire

Profile

I am an ice sheet and climate modeller working on linking past and future ice sheet changes through the development of new Artificial Intelligence and Uncertainty Quantification techniques climate-ice sheet interactions during the Quaternary. I currently hold a prestigious UKRI Future Leaders Fellowship which funds the SMB-Gen project aimed at Constraining projections of ice sheet instabilities and future sea level rise

I currently work only on Wednesday Afternoons, Thrusdays and Fridays. 

Short Bio: I did my PhD at the University of Bristol with Professor Paul Valdes and Professor Tony Payne on modelling the climate and ice sheets during the last deglaciation. It is during my PhD that I discovered the mechanism 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 have also pioneered the use of uncertainty quantification in modelling past climate and ice sheet and was the Model Uncertainty working group leader within Past Earth Network (PEN) that brought statisticians and palaeoclimatologists together. I have been the co-leader of the PMIP Deglaciations working group since 2014 and was a topical editor for Geoscientific Model Development (GMD). I joined the University of Leeds in July 2013 as an Academic Research Fellow in Earth System modelling and became an Associate Professor in 2019. I have the pleasure to lead fantastic researchers within the Climate-Ice research group.
