Work Experience
September 2012-present : Associate Professor in Materials Chemistry at the “Sciences et Méthodes Séparatives (SMS)” Laboratory, Rouen Normandie University.
Teaching activities encompass solid state chemistry (inorganic chemistry, heterogeneous equilibria, crystallography) for bachelor students and advanced solid state physical chemistry (polymorphism, phase diagram and X-ray diffraction).
Research activities are focused on the study of polymorphism of organic materials in different media (variable temperature, host-guest assemblies, thin films).
August 2007-July 2012 : Research scientist at Laboratory of Polymer Chemistry, Université Libre de Bruxelles.
Main research project: Study and control of the supramolecular organisation of p-conjugated organic compounds in thin films for applications in electronics/opto-electronics (Solar cells, field-effect transistors, light-emitting diodes).
September 2006-June 2007 : Teaching in Physics and Chemistry for undergraduate students, via the private tuition association Acadomia (Indre-et-Loire, France).
September 2005-September 2006 : Engineer-Researcher at CEA Le Ripault, Monts, France (Military Applications Department).
Main research project: Structural characterization of organic compounds crystallized at low temperature.
September 2001-July 2005 : Thesis of Doctorate. "Study of the Polymorphism and the Solid State Miscibility in the series of Saturated Fatty Acids" performed at the C.P.M.O.H laboratory (now L.O.M.A. Laboratory), University Bordeaux I.
The thesis defence occurred on July 21st, 2005 at University Bordeaux I
October 2001-August 2005 : Teaching given during the Thesis at University Bordeaux I (63 hours of Directed Studies and 345 hours of Practical Studies given in electronics, mechanics, optics and data processing for undergraduate students).
