Born 1952 in Grenoble. Ing?nieur Civil (Ecole des mines de Paris, 1974), Ing?nieur G?ologue (Ecole des mines de Paris, 1977), Docteur Ing?nieur (Ecole des mines de Paris, 1979), Docteur d?Etat (Universit? Paris VI, 1989). Professor and researcher to the Ecole des mines de Saint-Etienne since 1977.

Research

In the past, sedimentology and mapping (Alps of Haute Provence, directed by Bernard Beaudoin, Ecole des mines de Paris), inversion of the geomagnetic data (directed by Vincent Courtillot and Jean-Luc Le Mou?l, Institut de Physique du Globe de Paris), geomorphology and mapping of the weathering formations on peridotites (directed by Jean Vogt and Jean-Pierre Lajoinie, BRGM, Noum?a, New Caledonia), petrology and geochemistry of skarns (Pyrenees, directed by Michel Fonteilles, University Paris VI and Albert Autran, BRGM; Docteur Ing?nieur thesis and Doctorat d??tat thesis).

Present Studies

Petrology and geochemistry of skarns, thermodynamics and mathematics applied to geology, self-organization in geology (columnar jointing of basalts, Forbes ogives in glaciers, banded skarns etc.), fluid-rocks interactions modeling (in collaboration with Daniel Garcia and Jacques Moutte), application to the petroleum industry and to CO2 storage, application to magma-rocks interactions. Structure of phase diagrams (linear programming, matroid theory, in collaboration with Jean-Marie Pla), application to the weathering of cements (in collaboration with Essa?d Bilal), geochemistry of polluted soils (in coll. with Jean-Luc Bouchardon), epistemology of geology, foundations of physics (relativity theory, concepts of time, space and movement). I initiated a research in the modeling of the biological reactions (specific immunity lymphocytes, in collaboration with Frederic Gruy and Claude Lambert).
