GM received his Diploma degree in physics from École Polytechnique Fédérale de Lausanne (EPFL), Lausanne, in 1990 and his Ph.D. degree in physics from the University of Neuchâtel, Neuchâtel, Switzerland, in 1995. From 1991 to 1995 and from 1997 to 2006, he was a research scientist at Observatoire Cantonal de Neuchâtel, where he became group leader in 2001. From 1995 to 1997, he was guest scientist at NIST, Boulder (CO). In 2007, he co-founded the Laboratoire Temps-Fréquence (LTF) at the University of Neuchâtel, Neuchâtel, Switzerland, where he is deputy director and Professor. His research interests include atomic spectroscopy, stabilized lasers, and frequency standards. He took part to the development of space qualified (Galileo EU GNSS system) and industrial lamp-pumped Rb clocks (1991-1995) and of the Swiss primary Cs continuous fountain (1999-2001). Present team and research projects. GM is responsible of a research team of approximately ten scientists and engineers at the Laboratoire Temps – Fréquence. This team is involved in several research projects on vapour-cell atomic clocks and stabilised lasers that are funded, among others, by the Swiss National Science Foundation (SNF), Innosuisse, the European Union (EU) and the European Space Agency (ESA). These projects are conducted in collaboration with approximately twenty Swiss and foreign specialized laboratories and private companies. More generally, the research, teaching and scientific communications activities involve frequent contacts with most Time & Frequency institutes over the world, especially those specialized on vapour-cell atomic spectroscopy, atomic clocks and stable lasers. Since 2001, he has been principal investigator or co-investigator of more than 50 externally-funded research projects. The group has demonstrated state-of-the-art compact and miniature vapour-cell atomic frequency standards.
