Mahé Perrette


I currently work in the Isipedia project, on climate data processing, interactive graphics, and more generally web development for the Isipedia website. In parallel, I am involved in sea-level research with Matthias Mengel and others modelling work on the Greenland ice sheet (see background bio below). I mainly use the python language and am an active contributor on github.

My work at PIK was initially motivated by using the past to help project the future, using probabilities and ensemble climate simulations (mostly unpublished work, but see also intercomparison projects with a climate model of intermediate complexity  here and there). I then looked more specifically into probabilistic sea-level projections, both at global (e.g. here and here) and regional (e.g. here) scales, including its policy-relevant applications (e.g. herehere and here) with the team of Malte Meinshausen at PIK. In the last years, I have been working on the Greenland ice sheet, which is a major contributor to future sea level rise. Up to how much exactly remains poorly constrained, due to our limited understanding of dynamic processes at its margins and interactions with the ocean (e.g. here).

In order to better characterize uncertainties associated with future Greenland contribution to sea level rise, I developed 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. This became the main topic of my PhD thesis (GREENRISE project, with Andrey Ganopolski and Stefan Rahmstorf as supervisors), yet to be completed.

In my time outside PIK, I occasionally work as an independent contractor, which gives me the chance to experience real-world issues related to the climate negotiations (with Climate Analytics) or sustainable development projects (e.g. with IISD).

From time to time, I also get the chance to be involved in cross-disciplinary work, such as related to the Anthropocene (project in Haus der Kulturen der Welt), as well as in miscellaneous art projects.
