Professor Berger is M.Sc. in Meteorology from M.I.T. (1971) and D.Sc. from the Université Catholique de Louvain (Belgium) (1973). He is ordinary profesor and head of the Institute of Astronomy and Geophysics Georges Lemaître at the Catholic University of Louvain where he lectures on meteorology and climate dynamics. He is doctor honoris causa from the University of Aix-Marseille III and was professor at the Vrij Universiteit Brussel and Université de Liége.

His main research is about modeling climatic changes at the geological and at the century time scales. He has made notable contributions to the astronomical theory of paleoclimates. The climate model that he has developed with his team is also used for simulating the response of the climate system to human activities and the possible impact of such man’s induced perturbations on the natural course of climate at the geological time scale.

André Berger was chairman of the International Climate and Paleoclimate Commissions and of some NATO scientific Panels. He was vice president of the European Geophysical Society. He serves on several national and international scientific committees dealing with climate and global change. He is, in particular, member of the scientific council of Gaz de France, member of the council of the Academia Europaea and foreign member of the Koninklijke Nederlandse Akademie van Wetenschappen.

Professor Berger is the author of "Le Climat de la Terre, un passé pour quel avenir?". He has edited 10 books on climatic variations and has published more than 150 papers on this subject. He is associate editor of Surveys in Geophysics and editorial board member of The Holocene, of Climate Dynamics, and of Earth and Planetary Science Letters.
