Dr. Jean-François Willart is a researcher at the CNRS, Unité Matériaux et Transformations, Université de Lille. His research focuses on the physical state of molecular materials in non-equilibrium conditions: glasses and glass transition, metastability, and the kinetics of phase transformations. His current specific theme includes solid-state amorphization and polymorphic transformations induced by mechanical milling. This direction also applies to current issues in therapeutic materials and pharmaceutical formulations.
