Sylvain BréchetSylvain Bréchet was born on October 13th, 1981 in Moudon (legal origin Epesses, VD, Switzerland).
He obtained a Master of Science in physics at EPFL in 2005. He went on to Cambridge for his PhD studies in theoretical cosmology from 2005 to 2009 under the supervision of Prof. Lasenby (FRS) and Prof. Michael Hobson at the Cavendish Laboratory of the University of Cambridge.
He went back to EPFL where he is since 2010 university lecturer and research scientist in the Institute of Condensed Matter Physics. He taught classical mechanics, special relativity and thermodynamics to mechanical, electrical engineering students and physics students.
He is currently writing a textbook in thermodynamics.
Philippe GilletPhilippe GILLET completed his undergraduate studies in Earth Science at Ecole normale supérieure de la rue dUlm (Paris). In 1983 he obtained a PhD in Geophysics at Université de Paris VII and joined Université de Rennes I as an assistant. Having obtained a State Doctorate in 1988, he became a Professor at this same university, which he left in 1992 to join Ecole normale supérieure de Lyon.
The first part of his research career was devoted to the formation of mountain ranges particularly of the Alps. In parallel, he developed experimental techniques (diamond anvil cells) to recreate the pressure and temperature prevailing deep inside planets in the lab. These experiments aim at understanding what materials make up the unreachable depths of planets in the solar system.
In 1997, Gillet started investigating extraterrestrial matter. He was involved in describing meteorites coming from Mars, the moon or planets which have disappeared today and explaining how these were expelled from their original plant by enormous shocks which propelled them to Earth. He also participated in the NASA Stardust program and contributed to identify comet grains collected from the tail of Comet Wild 2 and brought back to Earth. These grains represent the initial minerals in our solar system and were formed over 4.5 billion years ago. He has also worked on the following subjects:
Interactions between bacteria and minerals.
Solid to glass transition under pressure.
Experimental techniques: laser-heated diamond anvil cell, Raman spectroscopy, X-ray diffraction with synchrotron facilities, electron microscopy.
Philippe Gillet is also active in science and education management. He was the Director of the CNRS Institut National des Sciences de lUnivers (France), the President of the French synchrotron facility SOLEIL and of the French National Research Agency (2007), and the Director of Ecole normale supérieure de Lyon. Before joining EPFL he was the Chief of Staff of the French Minister of Higher Education and Research.

Anirudh Raju NatarajanAnirudh received a B.Tech. in Metallurgical and Materials Engineering from the Indian Institute of Technology, Madras, a M.S in Materials Science and Engineering from the University of Michigan, Ann Arbor and a Ph.D. in Materials from the University of California, Santa Barbara. He set up the laboratory of materials design and simulation (MADES) at EPFL in 2022. His research interests are in the computational design and discovery of advanced engineering materials.
Christian GruberOriginaire de Neuchâtel, Christian Gruber est né à Orbe (VD) le 20 juillet 1939. Il étudie la physique à l'Université de Lausanne où il obtient son diplôme en 1963. Il poursuit ses études à l'Université de Princeton, aux Etats-Unis, tout en fonctionnant comme assistant: il y fait un Master en 1965 puis un doctorat, Ph. D. en physique théorique avec le prof. A. S. Wightmann en 1968.
Il est ensuite boursier à l'Institut des Hautes Etudes Scientifiques à Bures-sur-Yvette (France). Premier assistant au Laboratoire de physique théorique à l'EPFL, de 1971 à 1974, il est nommé professeur titulaire en 1975, puis extraordinaire neuf ans plus tard et enfin, professeur ordinaire en 1987. Chef du département de 1988 à 1990, il prend, depuis 1990, la direction de l'Institut de physique théorique.
Son enseignement porte sur la mécanique, la thermodynamique, la physique statistique, la physique quantique, et la relativité générale. Il poursuit des recherches dans le domaine des résultats rigoureux en mécanique statistique : propriétés des états d'équilibre, systèmes sur réseaux, systèmes coulombiens; études sur les transitions de phase, diagrammes de phase et tension superficielle. Il a dirigé plusieurs thèses sur la mécanique statistique classique et quantique de l'équilibre.
