Nicolas Grandjean
Nicolas Grandjean received a PhD degree in physics from the University ofNice Sophia Antipolis in 1994 and shortly thereafter joined the French National Center for Scientific Research (CNRS) as a permanent staff member. In 2004, he was appointed tenure-track assistant professor at the École polytechnique fédérale de Lausanne (EPFL) where he created the Laboratory for advanced semiconductors for photonics and electronics. He was promoted to full professor in 2009. He was the director of the Institute of Condensed Matter Physics from 2012 to 2016 and then moved to the University of California at Santa Barbara where he spent 6 months as a visiting professor. Since 2018, he is the head of the School of Physics at the EPFL. He was awarded the Sandoz Family Foundation Grant for Academic Promotion, received the “Nakamura Lecturer” Award in 2010, the "Quantum Devices Award” at the 2017 Compound Semiconductor Week, and “2016 best teacher” award from the EPFL Physics School. His research interests are focused on the physics of nanostructures and III-V nitride semiconductor quantum photonics.
Michael Graetzel
Professor of Physical Chemistry at the Ecole polytechnique fédérale de Lausanne (EPFL) Michael Graetzel, PhD, directs there the Laboratory of Photonics and Interfaces. He pioneered research on energy and electron transfer reactions in mesoscopic systems and their use to generate electricity and fuels from sunlight. He invented mesoscopic injection solar cells, one key embodiment of which is the dye-sensitized solar cell (DSC). DSCs are meanwhile commercially produced at the multi-MW-scale and created a number of new applications in particular as lightweight power supplies for portable electronic devices and in building integrated photovoltaics. They engendered perovskite solar cells (PSCs) which turned into the most exciting break-through in the history of photovoltaics. He received a number of prestigious awards, of which the most recent ones include the RusNANO Prize, the Zewail Prize in Molecular Science, the Global Energy Prize, the Millennium Technology Grand Prize, the Marcel Benoist Prize, the King Faisal International Science Prize, the Einstein World Award of Science and the Balzan Prize. He is a Fellow of several learned societies and holds eleven honorary doctor’s degrees from European and Asian Universities. His over 1500 publications have received some 220’000 citations with an h-factor of 218 (SI-Web of Science) demonstrating the strong impact of his scientific work.
Paul Muralt
Paul Muralt received a diploma in experimental physics in 1978 at the Swiss Federal Institute of Technology ETH in Zurich. He accomplished his Ph.D. thesis in the field of commensurate-incommensurate phase transitions at the Solid State Laboratory of ETH. In the years 1984 and 1985 he held a post doctoral position at the IBM Research Laboratory in Zurich where he pioneered the application of scanning tunneling microscopy to surface potential imaging. In 1987, after a stay at the Free University of Berlin, he joined the Balzers group in Liechtenstein. He specialized in sputter deposition techniques, and managed since 1991 a department for development and applications of Physical Vapor Deposition and PECVD processes. In 1993, he joined the Ceramics Laboratory of EPFL in Lausanne. AS group leader for thin films and MEMS devices, he specialized in piezoelectric and pyroelectric MEMS with mostly Pb(Zr,Ti)O3 and AlN thin film. His research interests are in thin film growth in general, and more specifically in property assessment of small ferroelectric structures, in integration issues of ferroelectric and other polar materials, property-microstructure relationships, and applications of polar materials in semiconductor and micro-electro-mechanical devices. More recently he extended his interests to oxide thin films of ionic conductors. The focus in piezoelectric thin films was directed towards AlN-ScN alloys. He gives lectures in thin film processing, micro fabrication, and surface analysis. He authored or co-authored more than 230 scientific articles. He became Fellow of IEEE in 2013. In 2005, he received an outstanding achievement award at the International Symposium on Integrated Ferroelectrics (ISIF), and in 2016 the B.C. Sawyer Memorial award.
Chairman of the International Workshops on Piezoelectric MEMS(http://www.piezomems2011.org/)
Mohammad Khaja Nazeeruddin
Dr. Md. K. Nazeeruddin received M.Sc. and Ph. D. in inorganic chemistry from Osmania University, Hyderabad, India. He joined as a Lecturer in Deccan College of Engineering and Technology, Osmania University in 1986, and subsequently, moved to Central Salt and Marine Chemicals Research Institute, Bhavnagar, as a Research Associate. He was awarded the Government of Indias fellowship in 1987 for study abroad. After one year postdoctoral stay with Prof. Graetzel at Swiss federal institute of technology Lausanne (E P F L), he joined the same institute as a Senior Scientist. His current research focuses on Dye-sensitized solar cells, Hydrogen production, Light-emitting diodes and Chemical sensors. He has published more than 380 peer-reviewed papers, ten book chapters, and inventor of 40 patents. The high impact of his work has been recognized with invitations to speak at over 80 international conferences, including the MRS Fall (USA, 2006) and Spring 2011 Meetings, GORDON conference (2014), and has been nominated to the OLLA International Scientific Advisory Board. He appeared in the ISI listing of most cited chemists, and has more than 33'500 citations with an h-index of 89. He is teaching "Functional Materials" course at EPFL, and Korea University; directing, and managing several industrial, national, and European Union projects on Hydrogen energy, Photovoltaics (DSC), and Organic Light Emitting Diodes. He was awarded EPFL Excellence prize in 1998 and 2006, Brazilian FAPESP Fellowship in 1999, Japanese Government Science & Technology Agency Fellowship, in 1998, Government of India National Fellowship in 1987-1988. Recently he has been appointed as World Class University (WCU) professor by the Korea University, Jochiwon, Korea (http://dses.korea.ac.kr/eng/sub01_06_2.htm) and Adjunct Professor by the King Abdulaziz University, Jeddah, Saudi Arabia.
Yves Revaz
Yves Revaz est maître d'enseignement et de recherche au laboratoire d'astrophysique (LASTRO) de l'EPFL. Après des études à l'EPFL, il a soutenu une thèse de doctorat intitulée: "Dynamique des régions externes des galaxies spirales et contraintes sur la matière noire" à l'Observatoire de Genève, sous la direction du Prof. Daniel Pfenniger. Il a ensuite travaillé à l'Observatoire de Paris, au LERMA (Laboratoire d'Etudes du Rayonnement et de la Matière en Astrophysique et Atmosphères) sous la supervision de la Prof. Françoise Combes et s'est intéressé aux écoulement froids dans les amas de galaxies. Il a rejoint le LASTRO en 2007, où, en collaboration avec la Prof. Pascale Jablonka, il a développé un nouveau code TreePM/SPH chemo-dynamique appelé GEAR, dans le but d'étudier l'évolution chimique des galaxies. Sa recherche se focalise actuellement sur l'évolution des galaxies naines et leur lien avec la cosmologie. Yves Revaz et aussi l'auteur de pNbody, une librairie python parallélisée dédiée à l'analyse de larges systèmes N-corps.
Georges Meylan
Après une thèse en astrophysique, en 1985, à l'Observatoire astronomique de l'Université de Genève, Georges Meylan séjourne en tant que postdoc à l'Université de Californie à Berkeley, USA, et au siège de l'Observatoire Européen Austral (ESO) à Munich, Allemagne. Il occupe ensuite des positions d'astronome senior à l'ESO à Munich et au Space Telescope Science Institute (STScI) à Baltimore, USA. Depuis août 2004, il occupe la chaire d'astrophysique de l'EPFL.
Sa recherche porte sur la cosmologie observationnelle, incluant le phénomène de lentilles gravitationnelles, les quasars et leurs galaxies hôtes, la formation et l'évolution des galaxies tout au long de l'évolution de l'Univers, la dynamique stellaire et l'étude des populations stellaires proches et lointaines.
