Laurens Siebbeles (1963) is leader of the Opto-Electronic Materials Section and deputy head of the Dept. of Chemical Engineering at the Delft University of Technology in The Netherlands. His research involves studies of the motion of electrons in novel nanostructured materials that have potential applications in e.g. solar cells, light-emitting diodes and nanoelectronics. Materials of interest include organic nanostructured materials, semiconductor quantum dots, nanorods and two-dimensional materials. Studies on charge and exciton dynamics are carried out using ultrafast time-resolved laser techniques and high-energy electron pulses in combination with quantum theoretical modeling.

Peter Strasser is the chaired professor of �Electrochemistry for energy conversion and storage� at the Chemical Engineering Division of the Department of Chemistry at the Technical University of Berlin. Prior to his appointment, he was Professor at the Department of Chemical and Biomolecular Engineering at the University of Houston. Before moving to Houston, Prof. Strasser served as Senior Member of staff at Symyx Technologies, Inc., Santa Clara, USA. In 1999, Prof. Strasser earned his doctoral degree in Physical Chemistry and Electrochemistry from the �Fritz-Haber-Institute� of the Max-Planck-Society, Berlin, Germany, under the direction of the 2007 Chemistry Nobel Laureate, Professor Gerhard Ertl. In the same year, he was awarded the �Otto-Hahn Research Medal� by the Max-Planck Society. In 1996, Dr. Strasser was visiting scientist with Sony Central Research, Yokohama, Japan. He studied chemistry at Stanford University, the University of Tuebingen, and the University of Pisa, Italy. Professor Strasser is interested in the fundamental Materials Science and Catalysis of electrified liquid solid interfaces, in particular for renewable energy conversion, energy storage, production of fuels and chemicals.

Ulrike Woggon studied Physics at the Friedrich-Schiller University Jena and the Humboldt-University in Berlin, Germany. In 1985 she received her PhD in Experimental Physics from the Humboldt-University in Berlin. In 1992 she was awarded with a grant for habilitation by the German National Science Foundation (DFG) and went to the group of Prof. Klingshirn were she conducted research on semiconductor quantum dots using various methods of ultrafast laser spectroscopy and nonlinear optics. In 1995 she got the habilitation from the University of Kaiserslautern with a thesis on "Optical Properties of Semiconductor Quantum Dots" which has been published as a monograph in Springer Tracts in Modern Physics in 1996. From 1993 to 1997 she was in charge of a research group on optical spectroscopy of II-VI quantum dots at the Institute of Applied Physics at the University of Karlsruhe. In 1997 she became a full-time Professor at the Department of Physics in Dortmund, heading a group of about 10 members working on problems of quantum coherence in semiconductor nanostructures, photonic structures and microsphere cavities, single-dot spectroscopy at nanocrystals and quantum dots and quantum-dot based devices. In 2008, she became a Professor at the Institute of Optics and Atomics Physics of the Technical University Berlin (TU). Ulrike Woggon has published more than 190 peer-reviewed journal papers and several book chapters. Her current research interests are focused on ultrafast spectroscopy of semiconductor quantum dots, on nanophotonics, in particular semiconductor nanostructures of mixed 0D-2D dimensionality, and nanoplasmonics with hybrid materials. She is a member and Fellow of the Optical Society of America (OSA), a member of the Material Research Society (MRS), and the German Physical Society (DPG). For OSA she was one of the Program Chairs of the International Quantum Electronics Conference (IQEC), San Francisco 2004 and served several times as committee member in the QELS subcommittee "Nanooptics and Nanoplasmonics" in 2000 (San Francisco), 2001 (Baltimore), 2006 (Long Beach), and 2008 (San Jose).

Celso de Mello Donega is an Associate Professor in the Chemistry Department of the Faculty of Sciences at Utrecht University in the Netherlands. His expertise is in the field of synthesis and optical spectroscopy of luminescent materials. His research is focused on the chemistry and optoelectronic properties of nanomaterials, with particular emphasis on colloidal nanocrystals and heteronanocrystals.

Roel van de Krol is head of the Insitute for Solar Fuels at the Helmholtz-Zentrum Berlin fuer Materialien und Energie (HZB), and professor at the Chemistry Department of TU Berlin. After earning his PhD from TU Delft in 2000 and a postdoctoral stay at M.I.T. (USA), he returned to TU Delft where he was an assistant professor until 2012. At HZB, his research focuses on the development of materials and devices for the photoelectrochemical conversion of sunlight to chemical fuels. Understanding how surface and bulk defects in thin films and nanomaterials affect light absorption, charge transport, recombination and catalytic activity is at the heart of these efforts.
