Research interests

My main research field is modeling of the ice-flow of glaciers and ice-sheets. In my PhD thesis (LGGE Grenoble, France) I was working on modeling the ice flow dynamics of alpine-type glaciers. Some model improvements have been implemented and several models have been compared on different types of glaciers in order to get a better understanding of which type of model should be used with which particular type of glacier. Elmer/Ice, a full Stokes model, was among these models. Later some of these models have been applied to the Mer de Glace glacier as a part of a survey for the French national electricity board (EDF) planning to relocate their water catchment point in view of the glacier's shrinkage. Some time was also spent on the study of a volcano glacier in Ecuador.
I have participated regularly to field campaigns. This included measurements of mass balance, velocity and topography as part of the surveying tasks of the French glacier observatory and a radar campaign on the Cotopaxi volcano glacier in Ecuador.
In my postdoc position in Canada we were working on ice calving. I participated in a field campaign in the Torngat Mountains (Northern Labrador, Canadian Arctic) with the aim to reassess some of the small remaining cirque glaciers by GPS and GPR measurements. Additionally I was participating in the analysis and interpretation of the field data from a campaign on the Belcher glacier (Devon Icecap, Canadian Arctic).
In my next postdoc position in Rovaniemi (Finland) I was working on different ice-flow modeling projects: The full-Stokes thermo-mechanically coupled ice-flow model Elmer/ice was used to study the dynamics of the glacier inside Scharffenbergbotnen valley, Dronning Maud Land, Antarctica and we concluded that only the existence of a pronounced ice fabric may explain the present day surface velocity distribution in this area. Within the SVALI and SvalGlac projects I was conducting modeling work on the Vestfonna ice-cap/Nordaustlandet (Svalbard) and doing fieldwork at Paierlbreen glacier/Hornsundbay (Southern Spitzbergen). A time-lapse camera was installed to study calving.
Now, at the FMI (Helsinki, Finland) I am continuing my modeling work within SVALI (WP 3 - Understanding present changes and understanding the future) on the Vestfonna ice-cap with Elmer/Ice. Focus is the understanding of basal processes leading to fast-flowing outlet glaciers or surgeing glaciers and the role of temperature in such processes. A second topic is the study of the sensitivity of coupling the ice-flow model to a surface mass balance model. In addition I am involved in a study about the understanding of melt in Greenland.
