Biography

After graduating as an Engineer in Materials Engineering from the National Institute of Applied Sciences of Lyon (INSA), I moved to public research and then to the profession of teacher-researcher. My doctorate, I obtained it in 1985 in one of the biggest centers of catalysis in France, the IRC in Lyon (Institute of Research on Catalysis, currently called IRCELyon, a CNRS laboratory). Then I spent 4 years abroad in Belgium (Namur) working closely with the company TOPSOE in Denmark on a European project (TOPSOE, it is one of the major actors of Chemistry and Catalysis in Europe). At that time, much work had already been done on the means of improving the properties of these extraordinary materials, namely zeolites. We were interested in optimising their acidity and their catalytic lifetime by performing controlled dealumination. I then began to work with Nuclear Magnetic Resonance (NMR), and more specifically on the development of methods of studying so-called "quadrupole" nuclei, such as aluminum (Al-27), which was very important for understanding the properties of these modified zeolites . I then joined in 1989 a laboratory of physics at the University of Lille, where with Prof. Jean-Paul Amoureux, I continued to develop NMR methods of quadrupole nuclei. Thanks to this stay of about 10 years in Lille, I became reconized in the NMR community particularly for my contribution to the development and the diffusion of the technique NMR-MQMAS, which allows to obtain high resolution spectra on quadrupole nuclei. I then joined as a professor in 1999 the Laboratory Catalysis and Spectrochemistry at ENSICAEN, to implant the NMR technique and its applications to various types of catalysts, with of course always the zeolites among these catalysts. From 2003 to 2007, I held the position of Director of the Laboratory at a time when serious threats hung over his survival because of his small size. We then worked to create a laboratory of excellence, which today is recognized among the best by the HCERES (the agency of evaluation of the research in France). For this reason, we have cultivated our specificity in the field of Operando spectroscopies which make it possible to follow the different stages of the life of a catalyst during its operation (for example in a catalytic converter). The RMN operando was also developed during this period, with successes especially in the framework of industrial collaborations. The "zeolite" theme was strongly reinforced with the arrival at the Laboratory of Svetlana Mintova and Valentin Valtchev, two CNRS researchers, specializing in the synthesis and modification of these materials. A team has thus been created around the rational design of zeolite materials especially for catalysis applications, but not only. It is a major axis of today's lab. My activity was diversified by incursions in the field of vibrational spectroscopy Infrared. Zeolites have always been one of my favorite research themes. I was for 6 years the president of the association "Groupe Français des Zéolithes" which brings together all the francophone players in the sector. Today, and since September 1, 2016, I again occupy the position of director of this laboratory, with the ambition to cultivate the excellence of its fundamental research, our core business, but also to make it a major players in partnership research in Normandy, thanks to our new, but strong involvement in the Institut Carnot normand ESP (Energy Systems of Propulsion), of which the accreditation has just been renewed .
