Prof. Dr. Ralph Michael KRUPKE

Helmholtz University, Eggenstein-Leopoldshafen, Germany, EU

Electronic and Optical Properties of Molecular Nanostructures, science and applications of carbon nanotubes and graphene

Research group leader at the Institute of Nanotechnology at the Karlsruher Institut of Technology (KIT) and Professor for Molecular Nanostructures at the Materials Science Department at the Technische Universität Darmstadt (TUD), Darmstadt, Germany, EU.

He received his Diploma in Physics (in 1995) from theUniversity Karlsruhe (Germany, EU) and his PhD-degree in Physics from the University of Tel Aviv (Israel).  In the period 2000-2004 he was a research associate at the Forschungszentrum Karlsruhe (FZK) and from 2005-2010 a Young-Investigator-group leader at FZK/KIT.

At the NANOCON 2013 conference Ralph Krupke will present a key-note lecture at the Session A - Preparation
and Properties of Nanostrutures.
