Studies at the Swiss Federal Institute of Technology in Zurich (ETHZ), Switzerland. After graduating in crystallography in 1966, he prepared his PhD thesis in the same institution under the direction of Prof.. A. Niggli which he obtained in 1972. For three years he continued his research at the Lawrence Berkeley Laboratory in California in the laboratory of Prof. D. H. Templeton, a well-known specialist in the field of resonant scattering. Back in Switzerland, he joined the newly created Institute of Crystallography at the University of Lausanne under the direction of Prof.. D. Schwarzenbach. In 1991 he was appointed full professor and in 1999, director of the Institute of crystallography. In 2003, his unit was transferred to the Ecole Polytechnique Fédérale in Lausanne (EPFL) where he was appointed professor.
G. Chapuis has chaired numerous committees in national and international organisations in the field of crystallography. In particular, he chaired the committee of aperiodic structures of the International Union of Crystallography (IUCr). He is also a member of the Education Committee of that organization. He also chaired the Swiss Society of Crystallography.
G. Chapuis is co-editor of the Journal Acta Crystallographica and participates in many committees for various readings of academic journals devoted to crystallography and solid state physics.
His research areas cover more specifically the theoretical and experimental study of aperiodic structures, especially incommensurate structures by diffraction and molecular dynamics. He is the author of over two hundred scientific papers published in international peer-reviewed journals. Moreover G. Chapuis is dedicated to the development of interactive teaching in crystallography using new communication technologies available on the Internet.
Riccardo Rattazzi
Riccardo Rattazzi was born in Novara (Italy) in 1964. He studied physics at the University of Pisa, where he received the Laurea cum laude in 1987, and at the Scuola Normale Superiore where he received the Diploma in Scienze and carried out graduate research in theoretical physics. After having been a post-doctoral research associate at the Lawrence Berkeley Laboratory, at Rutgers University and at CERN, in 1998 Riccardo obtained a permanent research position at the Istituto Nazionale di Fisica Nucleare in Pisa. From 2001 to 2006 he was a staff member at the Theory Division of CERN. In 2006 he was appointed professor of physics at EPFL.
Marco Grioni
Marco Grioni was born in Milan (Italy) where he graduated in 1982. He has occupied research positions at Minneapolis (USA), Nijmegen (The Netherlands), Orsay (France) and Neuchâtel, where he became Privat Docent in Solid State Physics in 1994. Since 1996 he is at EPFL, where he teaches physics to undergraduate and graduate students. He is acting director of the Laboratory of Electron Spectroscopy of IPN, and an adjunct professor from 2005.
His research interests concern the electronic properties of novel materials,namely high-temperature superconductors, low-dimensional metals, and heavy fermion compounds, which he investigates by high-resolution photoemission (ARPES), ultrafast time-resolved ARPES, and photon-in photon-out synchrotron-based spectroscopies. Author of approx. 220 scientific articles, he is actively involved in the development of new instruments. From 2003 to 2006 he was the chairman of the users organization of the European Synchrotron Radiation Facility (ESRF Grenoble). Between 2010 and 2017 he served as chairman of the scientific advisory committee of the french national synchrotron light source SOLEIL
