Benoît Marie Joseph Deveaud
Benoît Deveaud est maintenant Directeur Adjoint à l'Enseignement et la Recherche, Ecole Polytechnique Palaiseau.
Benoît Deveaud est né en France en 1952. Il est admis en 1971 à l'Ecole Polytechnique de Paris et s'y spécialise en physique. En 1974, il entre au Centre National d'Etudes des Télécommunications. Il mène à la fois les études sur les centres profonds dans les semi-conducteurs III-V, et poursuit ses études de physique en préparant un diplôme d'études approfondies en physique des solides. En 1984, il soutient sa thèse de doctorat à l'Université de Grenoble.
Entre-temps, son équipe s'intéresse aux microstructures et lance une recherche sur les propriétés structurales et optiques des super réseaux à base d'arséniure de gallium. Ces études mettent en évidence par exemple le transport vertical dans les superréseaux ou la quantification des énergies de transition dans un puits quantique. En 1986 il rejoint l'équipe de Daniel Chemla aux Bell Laboratories (Holmdel USA) et participe à la mise au point de la première expérience de luminescence ayant une résolution temporelle meilleure qu'une picoseconde. Il étudie les processus de relaxation ultra-rapide dans les puits quantiques.
Rentré en France, au CNET, en 1988, il dirige un laboratoire d'études ultra-rapides, portant sur les propriétés optiques et électroniques des matériaux semi-conducteurs.
Nommé professeur en physique à l'EPFL en octobre 1993, son équipe de recherche étudie la physique des processus ultrarapides dans les micro- et nanostructures et les composants qui les utilisent.
Il a dirigé l'Institut de Micro et Optoélectronique depuis 1998 puis l'Institut de Photonique et électronique quantique de 2003 à 2007. Son équipe participe activement au Pôle national de Recherche "Quantum Photonics" dont il a été le Directeur Adjoint de 2001 à 2005 puis le Directeur de 2005 à 2013.
Il a été Doyen pour la recherche à l'EPFL de 2008 à 2014.
De 2014 à 2017, il a dirigé l'Institut de Physique.
Il a été editeur divisionnaire de Physical Review Letters de 2001 à 2007.
Raphaël Butté
Raphaël Butté was born in Paris, France, in 1973. He received the PhD degree from the University Claude Bernard, Lyon, France, in 2000 for his research on the structural and optoelectronic properties of hydrogenated nanostructured silicon thin films with potential applications for photovoltaics and thin film transistors. He then moved to the University of Sheffield (2000-2003), UK, to work as postdoctoral research associate in the group of Prof. Maurice S. Skolnick (Fellow of the Royal Society). His research shifted to the optical properties of III-V semiconductors with a main focus on the nonlinear optical properties of cavity polaritons occurring in GaAs-based microcavities driven under resonant optical excitation. In 2004, he moved to Ecole Polytechnique Fédérale de Lausanne (EPFL) as scientific collaborator in charge of optical spectroscopy at LASPE (http://laspe.epfl.ch/), a newly established laboratory directed by Prof. Nicolas Grandjean. In 2010, he became permanent member of staff (Scientific Collaborator and Lecturer). He was promoted to the position of Senior Scientist in 2016. His current research activity deals with planar waveguides, microdisks and photonic crystals made from III-nitride semiconductors. In particular, he is leading the activity focusing on: (i) the physics of exciton-polaritons in planar waveguides and (ii) high-β photonic crystal nanolasers. He is the author of 119 scientific articles published in peer-reviewed international journals, 14 publications published in peer reviewed journals following an international conference (Web of Science > 4500 citations, h-index: 36; Google Scholar > 6200 citations, h-index: 42) and 6 book chapters. He has given 30 invited talks in International Conferences/Winter-Summer Schools/Workshops. He has been the Publications Chair/Guest Editor of the Proceedings of the 5th International Workshop on Nitride semiconductors (IWN2008) and also served as Scientific Secretary of IWN2008 and of the 5th International Conference on Spontaneous Coherence in Excitonic Systems (ICSCE5). In 2012, he was one of the 149 scientists recognized by the Outstanding Referee program (http://publish.aps.org/OutstandingReferees) of the American Physical Society (APS) selected from a pool of roughly 60,000 currently active referees. Since September 2019, he is an Editorial Board Member of the newly launched open access APS journal, Physical Review Research. From September 2013 until December 2017, he was one of the Editors of the journal "Superlattices and Microstructures" (Elsevier). Since September 2015 he is a member of the Physics Doctoral School Teaching Committee. He was also a member of the EPFL Teaching Conference from September 2015 until August 2017.
Giulia Tagliabue
Dr. Giulia Tagliabue is an Assistant Professor at the Institute of Mechanical Engineering (IGM). She obtained her B.S. and M.S degrees cum laude in Mechanical Engineering from the University of Udine in Italy. Concurrently she also obtained the diploma from the Scuola Normale Superiore of Udine. In 2015 she obtained her PhD in Mechanical Engineering from ETH Zurich with a thesis on nanophotonic design for light-to-heat and light-to-charge conversion devices. In 2015 Dr. Tagliabue was awarded the Early Mobility Fellowship from the Swiss National Science Foundation and moved to Caltech as a PostDoctoral fellow. In 2017, thanks to the award of an Advanced Mobility Fellowship, she prolonged her stay at Caltech. Here, in collaboration with the Joint Center for Artificial Photosynthesis (JCAP) she investigated coupled light, heat and charge transfer processes in nanophotonic structures and low-dimensional materials for photoelectrochemical and photovoltaic sustainable energy conversion.
