My researches aim to observe and understand the impacts of climate change on mountain glaciers and polar ice caps. In response to global warming, glaciers are declining and contribute about a quarter of the current rise in mean sea level (3 mm/year). The retreat of glaciers is changing the hydrological regime of mountain regions, affecting water resources in some arid regions such as the Andes or the valleys of the Himalayas. Another motivation for studying glacier is their role as an indicator and climate integrator in regions where temperature and precipitation series are rare and not very homogeneous.

My preferred study areas are the High Mountains of Asia, the Andes, Alaska, Iceland or the Antarctic Peninsula. Thanks to the numerous in situ measurements made by our colleagues in Grenoble, the Mont-Blanc glaciers are an ideal site for validating new methodologies using satellite imagery.

I also wish to facilitate the glaciological community's access to satellite data tailored for their needs. This was the driver of the SPIRIT project during the 4th International Polar Year (SPOT5-HRS sensor). Currently, through the Pleaides Glacier Observatory (PGO) program conducted in collaboration with CNES, we try to facilitate access to very high resolution images of Pleiades.
