Short biography
Stephan Roche is ICREA Research Prof. working at the Catalan Institute of Nanosciences and Nanotechnology-ICN2 and the Barcelona Institute of Science and Technology. He leads the "Theoretical and Computational Nanoscience" group which focuses on quantum transport in Dirac materials (graphene and topological insulators). He pioneered the development of linear scaling computational approaches for wavepacket dynamics, Kubo conductivities, and Landauer-Büttiker conductance in disordered materials.
He studied Theoretical Physics at ENS and UJF (France), received a PhD in Physics in 1996 (CNRS), and worked in Japan, Spain and Germany. He was appointed Prof. assistant at UJF (2000) and CEA Researcher (2004), and received the Friedrich Wilhelm Bessel prize from the A.v. Humboldt Foundation (Germany). He is the PI of ICN2 in the GRAPHENE FLAGSHIP, and deputy leader of the Graphene Spintronics WP.
Research interests
At ICN2, S. Roche and his group theoretically explore exotic quantum transport in Dirac Matter including graphene and topological insulators. Main current interests include (i) the study of quantum interferences and decoherence mechanisms in presence of electron-phonon coupling and spin-orbit interaction, (ii) spin dynamics and spin-torques phenomena in heterostructures, (iii) spin Hall and quantum spin Hall effects, valley Hall effects in graphene and (iv) thermoelectricity in two-dimensional materials.
