I have developed my expertise in glaciological studies of high-altitude temperate and Polar regions as a member of the Glaciology Laboratory of the Earth and Environmental Sciences Department of the Université Libre de Bruxelles since 1977. For more than 40 years now, this laboratory has focused his activities on the study of physico-chemical properties of «interface ice», be it the «ice-bedrock», «ice-ocean» or «ice-atmospher» interface. My expertise is based on numerous “ice-oriented” field expeditions (16 in the Alps, 10 in Antarctica and 4 in the Arctic regions ) and on the development of equipments and analytical techniques dedicated to the multi-parametric study of ice rich in solid or liquid impurities : textures and fabrics, stable isotopes of oxygen and hydrogen, total gas content and gas composition, bulk salinity, major elements chemistry…The main objective of this research effort is a better understanding of initial and boundary conditions of large ice masses (continental or marine), together with a comprehensive approach of the processes governing their interactions with the climate, more specially in the framework of the potential impact of mankind on future climate at a global scale.
