Invited Speakers Plenary


L’OREAL R&I, FRANCE – Advanced Research

Odile SONNEVILLE-AUBRUN is Head of Skincare, Make-up & Hair Physical-Chemistry Laboratories at L’Oréal.
She was graduated from ESPCI (Ecole Supérieure de Physique et de Chimie Industrielle de la ville de Paris) in 1993. She obtained a Post-Master degree specialization in Soft Matter from Sorbonne University in 1994 and her PhD in Physical-Chemistry on biliquid foams from Sorbonne University in 1997. She has been working for L’Oréal Research for 25 years in the field of skincare, body hygiene, make-up & hair products innovation. Many of these innovations have been patented.
Since 2016, she has joined L’Oréal College of Experts and has contributed to internal trainings in Physical-Chemistry applied to cosmetics.
Her main research is focused on deep understanding of structure and properties of products from bulk to deposit on skin and hair and on formulation triggers exploration to deliver new products with high measured and perceived performance.  This knowledge of applied Physical-chemistry makes it possible to identify and understand the major breakthrough innovations launched by L’Oréal.

Andreas KLAMT, PhD

Prof. Andreas Klamt studied Physics at the University of Göttingen, Germany, and gained his Ph.D. in Theoretical Solid State Physics at the Max-Planck-Institute and the University of Stuttgart, in 1987. He joined Bayer AG in 1987, learned Computational Chemistry on the job, and was promoted to the Head of the Computational Chemistry Department in 1996. He left Bayer in 1999 to found COSMOlogic which is now part of Dassault Systèmes where he is Senior Scientific fellow. In 2005, he obtained his Habilitation in Physical and Theoretical Chemistry from the University of Regensburg where he currently holds the position of honorary professor.

Prof. Klamt is a pioneer in the prediction and quantification of solvation effects. As his first major achievement he invented the Conductor-like Screening Model COSMO, which is widely used in quantum chemistry for the quantification of solvation effects. He is the creator of the COSMO-RS method which combines a quantum chemical treatment of solutes and solvents with a fast and effective statistical thermodynamics procedure for the molecular surface interactions. His method enables the calculation of thermophysical data for liquid systems without any prior experiments. In recent years he has considerably extended the field of application of his method by developing new tools (COSMOplex and COSMOquick) which allows to predict the properties of relevant systems in formulation science such as micelles, ionic liquids, deep eutectic solvents, polymers and complex materials.

Werner KUNZ, PhD

Prof. Kunz is head of the chair of physical chemistry II at the University of Regensburg in Germany. His group is specialised in solution chemistry (complex liquids, their structures, and interfaces) and in green chemistry. The activities span from very fundamental research to applied and industrial chemistry with a special focus on product formulation. He is also owner of a company, the SKH GmbH, which develops new formulations for various small, medium sized, but also big international companies. Here the focus is on cosmetics, perfumes, cleaning agents and plant extraction.

At present, Prof. Kunz authored or co-authored 330 peer-reviewed publications, further to several patents, book chapters, book editions etc. Kunz’ h-index is 56 (Web of Science) and 67 (Google Scholar), his papers are currently cited more than 12.400 times (>17.000 according to Google Scholar). For his basic and applied research, he received several prizes, e.g., the Rhodia prize from the European Colloidal Society, the Gay-Lussac prize from the French government and the Steinkoff prize from the German Colloidal Society.
