Jean-François Sadoc is Professor at Paris-Sud University where he teaches crystallography and statistical physics. At the 'Laboratoire de Physique des Solides' in Orsay, his main fields of interest are disordered systems. In particular, he focuses on liquid crystal structures and metallic quasicrystals. In 1983 he was awarded the Winter-Klein prize for his work on metallic glasses by the French Sciences Academy.
Rémy Mosseri is Director of Research at the 'Centre National de la Recherche Scientifique' and studies the structural and electronic properties of quasicrystals at the 'Groupe de Physique des Solides' at Paris University in Jussieu. He is also interested in the history of physics. In 1992 he was awarded the Paul Langevin prize by the French Physical Society.
