Research interests
My work applies observational and modelling approaches to a wide rage of topics in Quaternary palaeoclimate, climate dynamics and glaciology. A particular focus is testing hypotheses on the atmosphere, ocean and cryosphere interactions responsible for abrupt climate change. My current research topics include:
1.    Constraining the spatial extent, timing and amplitudes of glacial abrupt climate change events, by compiling a global database of high-resolution marine, ice core and terrestrial records.  
2.    Using the observational data from 1. to constrain global climate model simulations and improve process understanding.
3.    Testing how Southern Ocean heat and carbon dioxide uptake responded to past abrupt climate change using Antarctic ice core data, marine cores and model simulations.
4.    Recovering ice core records from sub-Antarctic and Antarctic islands for reconstructing wind and sea ice changes in the Southern Ocean. In January 2016 we obtained the first ice cores from the Antarctic Balleny and Peter 1st Islands.
5.    Investigating whether the West Antarctic Ice Sheet collapsed during the Eemian using a 'genetic-clock' approach, in collaboration with benthic ecologists.
All of these topics also have implications for major open questions in Earth System Science: How do past rates of climate change and their impacts on ecosystems compare to future projections? Can current rates of heat and CO2 uptake by the Southern Ocean be sustained?  Is there a temperature threshold for the stability of the West Antarctic Ice Sheet
