Didier has joined R&D Formulation & Stability platform of Sanofi-Pasteur in 2011. He focuses his work on high throughput screening formulations, stability prediction using advanced kinetics, vaccine activity – structure relationship, particulate matter in vaccines and adjuvants process optimization and physic-chemical characterization. For more than 15 years in Sanofi R&D, Didier was dedicated on physical and biophysical characterization of active ingredients, freeze-dried products and monoclonal antibodies (mAbs, ADC). He developed novel X-ray diffraction and thermal analysis tools to study polymorphism and amorphous state in solid materials. His research interests are structural characterization and aggregation state determination using a variety of biophysical techniques (light scattering, flow-imaging, DSC and thermokinetics, fluorescence and infra-red spectroscopy, …. ). Didier implemented Biophysical lab and a lab-automation platform for bioproduct formulations. He is coatching young scientists and performed courses in several Universities.
