I have worked for the British Antarctic Survey since 2006, and have had a keen interest in all things Interglacial since that time (https://www.bas.ac.uk/profile/lsim/#publications). My Earth System Modelling group within my Ice dynamics and Paleoclimate Team runs what will be the UK’s CMIP7 model, alongside the CMIP6 and CMIP3 models, including for the UK’s Last Interglacial PMIP experiments. My group is currently implementing water tracers and isotopes in the UK’s CMIP7 UKESM2 model. I also work towards isotope modelling intercomparison work including the AWI-ESM, IPSL, and UKESM models (e.g. surfeit.ac.uk - website still under construction). Christian and I plan that this WG will substantively contribute to understanding of the role and response of the ice sheets and sea ice to Interglacial warmth.

By training a physicist, I have been working as a climate modeller at the Alfred Wegener Institute, Division of Climate Sciences, Department for Paleoclimate Dynamics for the last ~15 years. During that time I have worked with various models (COSMOS, MPI-ESM, AWI-ESM). At the moment our research group is preparing the third generation of the AWI-ESM for paleoclimate research. My focus has always been on warm climates from orbital to tectonic time scales and most of the time on model intercomparison. In PMIP4 I simulated the Last Interglacial climate with MPI-ESM. Furthermore, I have been responsible for the Alfred Wegener Institute's contribution to the Pliocene Model Intercomparison Project (PlioMIP, see also PAGES Magazine). PlioMIP1 and PlioMIP2 have been a tremendous success. My dream is that we can replicate the lively collaboration of PlioMIP in our PMIP WG interglacials. I look very much forward to co-chair this WG together with Louise, and to collaborate with all of you towards the next model-intercomparison for interglacial climates.

I am paleoclimatologist and paleoceanographer using micropaleontological tracers to reconstruct sea-surface conditions in high latitude environments of the Northern Hemisphere, with special attention paid to the seasonal signal of proxies with respect temperature, salinity, and sea ice. My main areas of interest concerning the present and past interglacial stages are the land-sea linkages to understand the relationships between ice, ocean, and climate, in general.

My interglacial interests are in improving comparisons of multi-model output with climate proxy data, to refine our understanding of past climate dynamics. In line with this aim, my group at Cambridge University is developing new reanalysis-based estimates of Holocene and Last Interglacial global climate change.  This is done by explicitly assimilating globally dispersed proxies into PMIP-class models, accounting for structural uncertainties in both datasets. Paired interests are in refining understanding of past ice-sheet—climate coupling and in developing physically based proxy-system models.
