Georges Calas is Professor (Emeritus) of Mineralogy, Sorbonne Université, Paris, France. He received in 1980 a Science Doctorate in Mineralogy from the University of Paris. He is Professor (Emeritus) of Mineralogy at Sorbonne Université (Paris) since 2001 and Senior member of the University Institute of France. Prior to that, he was CNRS research associate and then full Professor at the University Paris Diderot. He has been Allan Cox Visiting Professor at Stanford in 1992 and Invited Professor at Collège de France in 2014-2015.
As Scientific Advisor at the French Ministry of Higher Education and Research, he chaired the French Research network on “Glassy Materials” and the Regional Scientific Network on Oxide Materials/OXYMORE. He is on the Board of the French Geological Survey and member of the Stanford Environmental Molecular Science Institute.
Dr. Calas published about 350 peer-reviewed journal papers, conference proceedings and book chapters and organized about 80 Meetings. He is Associate Editor of the Journal of the American Ceramic Society. A former chairman of the “Physics of Minerals” Commission of the International Mineralogical Association, he was President of the French Society of Mineralogy and Crystallography and Vice-president of the European Mineralogical Union.
He is a member of the Academia Europaea and Foreign Fellow of the Royal Society of Canada. He received the Schlumberger Medal, Mineralogical Society of Great Britain. He was on the Board of Fellows of the Society of Glass Technology, and is Honorary Fellow of the Mineralogical Society of Great Britain and a Fellow of the Mineralogical Society of America, the Geochemical Society and the European Association for Geochemistry.
Dr. Calas and his group were among the first, in the early 80’s, to use synchrotron radiation to investigate the structure- properties relationships in silicate materials including glasses. In addition to mineralogical sciences, his research activity concerns functional glasses, cultural heritage, nuclear waste management and environmental sciences.
