Research Interests

Theory and modeling of materials. Current activities include atomistic simulations with quantum and classical models for the structural, vibrational, mechanical, electronic, optical properties of amorphous and nanostructured materials, fundamentals and applications of localization and transfer of nonlinear excitations.

Short Curriculum Vitae

George Kopidakis received a B.Sc. in Physics from the University of Crete and a Ph.D. in Condensed Matter Physics from Iowa State University in 1995. After his graduate work at Ames Laboratory-Iowa State University, USA, he worked as a research assistant professor at the Center for Atomic-Scale Materials Physics (CAMP), Dept. of Physics, Technical University of Denmark. He then moved to Laboratoire Leon Brillouin (CEA-CNRS), Saclay, France, initially with an individual Marie Curie EC post-doctoral fellowship and later as a CNRS research associate. He was a research associate at the Physics Dept. and a visiting associate professor at the Dept. of Materials Science and Technology, University of Crete, where he was appointed assistant professor in 2003. He is also affiliated researcher at FORTH since 2005.
