About

- JSPS Post-Doc fellow at the Dpt of Mechanical Engineering of the Nagaoka University of Technology, Japan (20011-2013).
Objectives: understanding of recrystallization mechanisms of ice in natural conditions (glaciers, ice sheets, ice shelves), in order to parameterize these processes and improve ice flow models.
Crystallographic studies of artificial and natural ice under various stress and deformation patterns. Focus will be done on the NEEM ice core, drilled in N-W Greenland from 2008 to 2011.

- Marie Curie Post-Doc fellow at the Glaciology Research Group of the University of Uppsala, Sweden (2009-2011), and  member of the NSINK project (Sources, sinks and impacts of atmospheric nitrogen deposition in the Arctic).
Objectives: to retrieve new ice cores from high elevation Svalbard sites and to conduct their physical and chemical analysis, giving specific attention to the historic accumulation of nitrogen compounds and isotopes in Svalbard ice fields.
By placing a suite of multidisciplinary lab results into the context of detailed field work, my work is aiming at generating integrated datasets that will help geophysicists and biologists to constrain the nitrogen mass balance in the Polar Regions.

- BELSPO Post-Doc fellow at the Glaciology Lab of the Université Libre de Bruxelles (2006-2009).
Objectives: investigating the dynamics of major cryospheric boundary zones, like e.g. the (1) marine ice and (2) basal ice environments, i.e. (1) ice accreting under ice shelves in relation with ocean circulation and (2) ice forming and deforming at the base of glaciers and ice sheets.

- PhD in Geology/Glaciology at the Glaciology Lab of the Université Libre de Bruxelles (2002-2005).
Worked essentially on the geochemical and physical processes occurring at the basal boundary layer of various glaciers from polar regions. First interested in the influence of subglacial deformation on the geochemical and physical properties of basal ice. Most of the studied ice samples were retrieved from subglacial tunnels dug from the margin of glaciers from the Dry Valleys in Antarctica. This work led to a geologically-oriented characterization of the relationships between debris stratigraphy, ice geochemical composition and ice crystallography at the base of polar glaciers.
