Group Leader
ICREA Prof. Stephan Roche is working at the Catalan Institute of Nanosciences and Nanotechnology (ICN2) and BIST. He leads the Theoretical and Computational Nanoscience group which focuses on physics of Dirac materials (graphene and topological insulators) and 2D materials-based van der Waals heterostructures. He pioneered the development of linear scaling quantum transport approaches enabling simulations of billion atoms-scale disordered models (www.lsquant.org). He studied Theoretical Physics at ENS and got a PhD (1996) at Grenoble University (France); worked in Japan, Spain & Germany; was appointed as assistant Prof. in 2000, CEA Researcher in 2004 and joined ICREA in 2009. He received the Friedrich Wilhelm Bessel prize from the Alexander von Humboldt Foundation (Germany). From 2013 till 2023, he has been very active in the Graphene Flagship, as leader of the work package SPINTRONICS and as DIVISION leader. Finally, he is leader and coordinator of the “Quantum Communications” activities at ICN2.
