Marianne Quiquandon (also published as Marianne Cornier) is a French metallurgist for the French National Centre for Scientific Research (CNRS), and a member of the structural metallurgy team in the Institut de Recherche de Chimie Paris (IRCP), a joint research institute of CNRS and Chimie ParisTech.
[1] Her research involves the study of quasicrystals in aluminum alloys and the crystallographic properties of generic twisted bilayers, with her husband Denis Gratias.
[2] Quiquandon earned a master's degree in 1981 at Pierre and Marie Curie University, and began work at CNRS in Michel Fayard’s group in the Centre d'Étude de Chimie Métallurgique (Vitry-sur-Seine), where she completed a Ph.D. in 1988 on the elastic dynamic diffraction theory of fast electrons by crystals and quasicrystals.
[3] She worked from 2000 to 2014 in the laboratory for the study of microstructures (LEM, a joint ONERA-CNRS laboratory, Châtillon) on the description of structural models of quasicrystals and approximant phases in alloys.
Quiquandon is a member of the Société philomathique de Paris [fr].
