Dr. Mathieu G. Silly is beamline Scientist at the TEMPO Beamline at the Synchrotron Soleil in France, since 2008. He is in charge with the development of pump probe experiment using high resolution photoemission spectroscopy to study transient phenomena in photoexcited materials. He was graduated from “Institut d’Optique Graduate School” (France) in 2000 and received his PhD Degree in surface science in 2004 from University of Paris XI (France). In 2005, he worked as a postdoc fellow at the ONERA on the optical properties of hBN wide band gap 2D semiconductor. He joined the synchrotron SOLEIL in 2006 to develop the time resolved photoemission spectroscopy on the TEMPO beamline. After being co beamline manager in 2017, he has been appointed head of LASER installation at the TEMPO beamline. His main research interests include the optical, electronic and chemical properties of 2D and nano materials. He is author/co-author of over 130 publications in refereed journals and he has an h-index of 27.
