Stephan Roche is ICREA Research Professor working at the Catalan Institute of Nanotechnology-ICN in Barcelona, and head of the “Theoretical and Computational Nanoscience” group which focuses on the theoretical exploration of quantum transport phenomena in materials such as graphene, organic crystals, or topological insulators.
After studying Theoretical Physics at the Ecole Normale Supérieure in France, he received a Ph.D. in Physics in 1996 working at CNRS, and then worked in Japan, Spain and Germany. In 2000, he was appointed as a Professor Assistant at UJF (France) and as a CEA Researcher in 2004. During his stay at the Nanoscience Institute- INAC/CEA, he supervised the “simulation platform” of the CHEMTRONICS program, in preparation of the NANOSIMULATION program. In 2009, he was awarded the Friedrich Wilhelm Bessel prize from the Alexander von Humboldt Foundation (Germany). He is the PI of ICN in the GRAPHENE FLAGSHIP initiative (www.graphene-flagship.eu)

Research Interests
|
|
At ICN, S. Roche and his group theoretically explore exotic quantum transport phenomena in low dimensional structures and complex materials including carbon nanotubes, DNA, graphene, organic crystals and topological insulators.
The targets of interest include the effect of chemical and topological disorders, as well as electron-phonon coupling and spin-orbit interaction on quantum interferences, localization phenomena and decoherence mechanisms.
A methodological research line consists in the development of innovative quantum transport computational approaches to describe charge, spin phonon, or polaron dynamics in complex matter.
The research activities of the group are closely connected to the experimental challenges endeavored at ICN including nanoelectromechanical systems, spintronics and phononics; as well as the establishment of a long collaborative research strategy with the “theory and simulation” group headed by Pablo Ordejon at CSIC.
