David López Diáz is a researcher in the Physical Chemistry Department. He carried out his PhD studies in the field of surface properties of Langmuir and Gibbs monolayers formed by binary mixtures of surfactants and polymers.
From 2008 to 2010, he was postdoctoral researcher in the Complex Fluids Group (Institute of Physics) in the National Autonomous University of Mexico. In this period he studied the rheological and micro-rheological properties of surfactant mixtures and he also synthetized Janus particles with asymmetrical properties.
