Olivier Schneider
After his thesis defense in particle physics in 1989 at University of Lausanne, Olivier Schneider joins LBL, the Lawrence Berkeley Laboratory (California), to work on the CDF experiment at the Tevatron in Fermilab (Illinois), first as a research fellow supported by the Swiss National Science Foundation, and later as a post-doc at LBL. He participates in the construction and commissioning of the first silicon vertex detector to operate successfully at a hadron collider; this detector enabled the discovery of the sixth quark, named "top". Since 1994, he comes back to Europe and participates in the ALEPH experiment at CERN's Large Electron-Positron Collider, as CERN fellow and then as CERN scientific staff. He specializes in heavy flavour physics. In 1998, he becomes associate professor at University of Lausanne, then extraordinary professor at the Swiss Institute of Technology Lausanne (EPFL) in 2003, and finally full professor at EPFL in 2010. Having worked since 1997 on the preparation of the LHCb experiment at CERN's Large Hadron Collider, which started operation in 2009, he is now analyzing the first data. He also contributes since 2001 to the exploitation of the data recorded at the Belle experiment (KEK laboratory, Tsukuba, Japan). These two experiments study mainly the decays of hadrons containing a b quark, as well CP violation, i.e. the non-invariance under the symmetry between matter and antimatter.
Benoît Marie Joseph Deveaud
Benoit Deveaud is now Research Director at Ecole Polytechnique in Palaiseau (France)
Benoît Deveaud was born in France in 1952. In 1971, he enters Ecole Polytechnique in Paris where he specializes in physics. In 1974, he joins the National Center for research in Telecommunications (CNET).
He undertakes at the same time studies on the main impurity centers in III-V semiconductors, and continues his studies in physics by preparing a diploma in solid state physics in Rennes. In 1984, he defends his PhD thesis at the University of Grenoble, under the supervision of Gérard Martinez. Meanwhile, his team gets interested in semiconductor microstructures and launches studies on the structural and optical properties of superlattices based on gallium arsenide. These studies highlight for example vertical transport in superlattices as well as the quantification of excitonic energies in a quantum well.
In 1986 he joins the team of Daniel Chemla in Bell Laboratories (Holmdel, USA) and takes part in the development of the first luminescence set-up having a temporal resolution better than 1 picosecond. He studies then ultrafast processes in quantum wells.
Returning to France in 1988, at CNET, he coaches a laboratory of high-speed studies, interested in the optical and electronic properties of semiconductor materials.
Appointed professor in Physics at EPFL in October 1993, his research team studies the physics of ultrafast processes in semiconductor micro and nanostructures and in devices that use them. He has been the Director the Institute of Micro and Optoelectronics since 1998, then of the Institute of Quantum Photonic and Electronics from 2003 to 2008.
His team takes an active part in the "Quantum Photonics" National Center of Competence in Research, of which he was the Deputy Director from 2001 to 2005 then the Director from July 2005 till the end of the NCCR in 2013
From 2008 till 2014 he has been Dean for Research at EPFL and president of the research commission.
Starting in 2014, he has been head of Physics, till his departure from EPFL in 2017.
He has been a divisional editor of Physical Review Letters from 2001 to 2007.
