Dr. Thomas Grange


Thomas is Chairman and Founder of nextnano Lab SAS, a Research & Development laboratory located in Grenoble, France. He is also Authorised Signatory (Prokurist) for nextnano GmbH.

Before founding nextnano Lab SAS, Thomas was working as Director of Research & Development at nextnano GmbH (2017-2021).

He is an expert on quantum cascade laser modeling using the non-equilibrium Green's function method.

Thomas was born in France and studied Physics at the École normale supérieure de Lyon (ENS Lyon) and at the École normale supérieure (ENS), Paris. He holds a bachelor (License) and a master (Maîtrise) degree in Physics from ENS Lyon and a Master in Quantum Physics degree from the ENS, as well as a PhD in Physics from Université Paris VI (Université Pierre-et-Marie-Curie). His PhD work was on the theory of electron-phonon interaction, polaron formation and dynamics in quantum dots in the group of Robson Ferreira and Gérald Bastard at the ENS. During his studies, he spent a few months with Danny Segal at the Imperial College London (UK) and with Lu J. Sham at the University of California, San Diego (USA).

Before joining nextnano in 2017, he worked for 8 years as a Postdoc. Half of this time he spent with a Humboldt Research Fellowship at the Walter Schottky Institute of the Technische Universität München (Germany) in the group of Peter Vogl on the modeling of quantum cascade lasers. At the Institut Néel (CNRS) in Grenoble (France) he was working in the Nanophysics and Semiconductors group of Alexia Auffèves on modeling of quantum dots and nitrogen-vacancy centers in diamond.
