Research Interests

My (on-going) PhD work was initially motivated by using the past to help project the future, using probabilities and ensemble climate simulations (mostly unpublished work, but see also EMICS intercomparison projects here and there).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. here, here and here) with the PRIMAP team. More recently, I have 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 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 have 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. This has become the main topic of my PhD thesis (GREENRISE project, with Andrey Ganopolski and Stefan Rahmstorf as supervisors).

I am also working within the PalMOD project, whose goal is to simulate a complete glacial cycle with state of the art climate models - a necessary validation for models otherwise used for future projections. My task consists in modelling ocean carbon cycle, to help understand large, yet partly unexplained drop in atmospheric CO2 during ice ages, a long-standing enigma in climate research.

I am increasingly interested in cross-disciplinary work related to the Anthropocene (e.g. project in Haus der Kulturen der Welt), involving not only climate but how humans interact with it, and among each others.


I am mostly working with the python language (as well as fortran 200X), and am an active contributor to the open-source community (e.g. dimarray package). Find me on github !
