Dominique Langevin is CNRS research director. She first worked at the Physics Laboratory of Ecole Normale Superieure in Paris. She was afterwards director of the Paul Pascal Research Center, CNRS laboratory in Bordeaux. She currently works at the Laboratoire de Physique des Solides in Orsay, France.Her main research topic is the study of liquid interfaces in the presence of surfactants, polymers and/or nanoparticles, with a special focus on interfacial rheology. She is presently involved in the study of the physical chemistry of foams and emulsions. She published about 400 articles in scientific journals. She is also active in teaching in various area of Physics: Optics, Thermodynamics and topics closer to her research, Formulation, Surfactants and Foams. She received among other awards a grand prix of the French Academy of Sciences, the silver medal of CNRS, the L’Oréal Unesco award for women in Science and the Overbeek gold medal. She is member of the Academia Europea.

• Common background.- Microemulsions.- Emulsions and foams.- Similarities, differences between emulsions and foams, emulsions and microemulsions.- Industrial applications.
