Dr René Williams


Assistant Professor, Molecular Photonics Group, Van’t Hoff Institute for Molecular Sciences, Faculty of Science, University of Amsterdam


Dr. Williams is assistant professor in the Molecular Photonics group of the HIMS at the Universiteit van Amsterdam (UvA) since 1999. In 1998 he worked with Prof. Nick J. Turro on triplet sensitization of commercial photoinitiators (at Columbia University in the city of New York). At the Max-Planck institut in Mülheim he worked with Prof. Silvia E. Braslavsky on opto-acoustics in 1997. In 1996 he did his PhD on buckyballs (C60) and electron transfer with Prof. Jan W. Verhoeven at UvA.
