Frank Scheffold is the head of the Soft Matter and Photonics Group in the Physics department at the University of Fribourg, Switzerland. He studied at the University of Konstanz in Germany, as well as the Weizmann Institute of Science (Israel, with Prof. J. Klein). He obtained his doctorate summa cum laude at the University of Konstanz, for research carried out with Prof. G. Maret at the Institute Charles Sadron (Strasbourg, France) and Konstanz. His research in the Soft Matter and Photonics Group focuses on the optics of complex systems, dynamic light scattering and diffuse light propagation, the dynamics, aggregation and phase behaviour of colloidal systems and the production and characterization of soft materials. He is currently a member of the Swiss National Research Council and the Steering Committee for “Polymers and Colloids” at the Swiss Chemical Society.
