Mahé Perrette works on a PhD at the Potsdam Institute for Climate Impact Research. His work was initially motivated by using the past to help project the future, using probabilities and ensemble climate simulations. He then looked more specifically into probabilistic sea-level projections, both at global and regional. More recently, he has been working on the Greenland ice sheet, which is a major contributor to future sea level rise, yet up to how much exactly remains poorly constrained, due to the limited understanding of dynamic processes at its margins and interactions with the ocean. In order to better characterize uncertainties associated with future Greenland contribution to sea level rise, he has been developing a numerical model as well as data analysis tools for its outlet glaciers and fjord system, featuring ice / ocean interactions in a topographically complex, fine-scale environment.
