Research Experience: 

My research interests include the study of ice-ocean-solid Earth interactions and their lasting impact on the Earth system, with a specific focus on modelling the Glacial Isostatic Adjustment (GIA) process and on sea level/ice sheet evolution from the Late Quaternary to the present. These efforts to model the evolution of the global climate system take advantage of a vast array of geophysical data (relative sea level reconstructions, space-geodetic measurements of crustal motion, time-dependent gravity measurements, etc.), and result in global reconstructions of past ice sheet cover and sea level evolution over the last glacial cycle (global and local), while providing constraints on the physical properties of the Earth’s interior.

Understanding the patterns of sea level evolution and variability through time is particularly important in the context of anthropogenic climate change. For instance, this work is used to constrain local estimates of future sea level change and to optimally remove from modern observations of sea level variability (tide gauges, satellite altimetry) the contamination of the signal due to the lasting impact of the glaciation/deglaciation cycles. Studies of the GIA process also provide surface boundary conditions necessary for the reconstruction of past climate states using climate models. This work helps us understanding the past behaviour of ice sheets and their present-day response to global climate change.

I also have a strong interest in the communication of climate change science to the public and in the media, as well as in the interface between science and policy-making.
