Gérard GremaudGérard Gremaud was born in Fribourg (Switzerland) in 1949. After classical studies at College St Michel in Fribourg, he received his diploma in physics engineering in 1974 and his PhD in 1981 at EPFL. From this date, he became responsible for research at EPFL (Swiss Federal Institute of Technology of Lausanne). He is then co-responsible for the Mechanical Spectroscopy Laboratory at the Institute of Physics of Complex Materials. In 2002, he became also chief of the service of physics teaching laboratories and physics classroom demonstrations of EPFL. In 2005, he obtained the title of Professor of EPFL. From 1976, he was teaching in the fields of acoustics, vibrations, metallurgical physics, thermodynamics, dislocation theory, metrology, physics laboratories, and of basic physics (mechanics, thermodynamics and introduction to quantum physics) and physics demonstrations. Since 2012, he is honorary professor of EPFL.
He was active in a variety of research fields : dislocation dynamics, structural phase transitions, mechanical and tribological properties at nanoscale, and mechanical properties of vibrated granular materials (mechanical-spectroscopy). In these fields, he has directed about ten PhD thesis. He is the author of numerous theoretical models which are largely cited. Specialized in acoustical spectroscopy techniques, he developped several original experimental techniques, such as the US-LF coupling technique (representative publications). His publications include about 130 research papers, 13 book chapters, 6 popular publications, 3 books as editor and 2 books as author.
In addition to about 40 invited lectures and conference talks in leading institutions worldwide, he has co-organized several international conferences and summer schools. Member of several scientific societies, he contributes also as referee for numerous scientific journals and several scientific research funding organisations. He was collaborating also during several years to two small companies in Switzerland, as administrator or president.
In 2011, Gérard Gremaud has been awarded the Zener prize and Zener Gold medal. This distinction recognizes important contributions in the field of Materials Science and Physics.
Christophe Marcel Georges GallandI studied at Ecole Polytechnique in Paris (X2003) and received my PhD in 2010 from ETH Zürich for a thesis in solid-state quantum optics with individual carbon nanotubes, in the Quantum Photonics Group of Prof. Ataç Imamoglu. As a postdoctoral researcher at Los Alamos National Lab (USA) I studied the photophysics of individual nanocrystal quantum dots in the groups of Victor Klimov and Han Htoon. I was investigating the mechanisms responsible for fluorescence fluctuations and how to control them. I then moved to the University of Delaware in the group of Michael Hochberg to work in the emerging field of integrated quantum optics. I was leading international projects such as the realisation of an on-chip source of quantum correlated photons integrating optical filters and demultiplexers. From 2013 to 2016, I was working at EPFL in the group of Prof. Kippenberg in the field of quantum optomechanics with an Ambizione Fellowship of the Swiss National Science Foundation (SNSF). My work focused on the creation of non-classical vibrational states of mesoscopic oscillators and on the amplification of vibrations in molecules. Since May 2017, I am leading the Laboratory of Quantum and Nano-Optics at EPFL as an SNSF-funded professor in the Institute of Physics. My team investigates two main phenomena: (i) the vibrational dynamics of molecules embedded in nanoscale plasmonic cavities, and (ii) non-classical correlations mediated by individual quanta of crystal vibrations at room-temperature. We employ state-of-the-art spectroscopic tools such as femtosecond lasers and single-photon counters to get new insights into sub-nanometer scale dynamics.
Lenka ZdeborováLenka Zdeborová is a Professor of Physics and of Computer Science in École Polytechnique Fédérale de Lausanne where she leads the Statistical Physics of Computation Laboratory. She received a PhD in physics from University Paris-Sud and from Charles University in Prague in 2008. She spent two years in the Los Alamos National Laboratory as the Director's Postdoctoral Fellow. Between 2010 and 2020 she was a researcher at CNRS working in the Institute of Theoretical Physics in CEA Saclay, France. In 2014, she was awarded the CNRS bronze medal, in 2016 Philippe Meyer prize in theoretical physics and an ERC Starting Grant, in 2018 the Irène Joliot-Curie prize, in 2021 the Gibbs lectureship of AMS. She is an editorial board member for Journal of Physics A, Physical Review E, Physical Review X, SIMODS, Machine Learning: Science and Technology, and Information and Inference. Lenka's expertise is in applications of concepts from statistical physics, such as advanced mean field methods, replica method and related message-passing algorithms, to problems in machine learning, signal processing, inference and optimization. She enjoys erasing the boundaries between theoretical physics, mathematics and computer science.
