Dr Lauren Gregoire

Profile

I am an ice sheet and climate modeller working on climate-ice sheet interactions during the Quaternary. 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 joined the University of Leeds in July 2013 to become an Academic Research Fellow in Earth System modelling and became a Lecturer in 2018 and Associate Professor in 2019. I currently co-lead the PMIP working group on the last deglaciation and I am Steering Commitee member of PalaeoARC. I am also a topical editor for Geoscientific Model Development (GMD).

Office hour: Tuesday 12pm- 1pm

Responsibilities

  • Deputy Director of Postgraduate Research Studies (computing projects). Drop-in Tues 12-1 pm

Research interests

I use the Glimmer-CISM and BISICLES ice sheet models and the FAMOUS and HadCM3 General circulation models of the MetOffice Unified model familly. My main research interests are:

  • Mechanisms of ice sheet instability
  • Abrupt climate change
  • Rapid sea level rise and Meltwater pulses
  • Quantifying uncertainty in complex models
  • The Last deglaciation (~ 23,000 to 7,000 years ago)
  • The Northern Hemisphere ice sheets; The British and Irish ice sheet

Leadership positions/responsibilities:

External PhD students:

  • Jamie O'Neill (co-supervisor; March 2018-; based at King's College London):  Sea level rise under climate change: modelling the Pliocene warm period for improved projections of the future.

Previous group members:

  • Ilkka Matero (primary supervisor; Oct 2014-2018): North American ice sheet collapse and abrupt climate change during the 8.2 kyr event.
  • Nigel Clifford (MRes, primary supervisor, 2015-2016): Impact of ice sheet freshwater release in the North Atlantic on the variability of European winter climate.
  • Alice Drinkwater (Research experience placement, co-supervisor, summer 2016). Anthropogenic effects on intense melt episodes over Greenland.
