I am an atmospheric physicist with the ecological interests of protecting our natural environment. After a scientific formation in material and surfaces Physics and a general engineer school, I did my phD (1999) at Grenoble University (Laboratoire de Glaciologie et de Géophysique de l’Environnement, now Institut de Géophysique de l’Environnement) on studying experimentally the interactions between ice cloud particles and atmospheric acid trace gases to better define the processes leading to the depletion of stratospheric ozone. I then did a first postdoc at Forschungszentrum Juelich in Germany to set-up a new chromatograph for PAN and PPN measurements, precursors of tropospheric ozone. I got a grant for a second postdoc at Harvard University in Steve Wofsy’s group where I studied thetransport of pollutants and CO2 by large convection systems through NASA field campaigns. In 2003, I came back to France to join LSCE (Laboratoire des Sciences du Climat et de l’Environnement) in Gif-sur-Yvette for my third postdoc, which focused on characterizing CO2 variability in the low atmosphere over Europe through airborne campaigns and modeling.

In 2005, I got named Physicienne-adjointe at Comité National des Astronomes et des Physiciens at OSU OVSQ (Observatoire de Versailles Saint-Quentin en Yvelines) / LSCE with 3 missions : observing (30%), teaching (20%) and performing research (50%), on the same thematic. In 2009, I changed my activities to focus on the urgent need to address urban environments : more than 70% of CO2 fossil fuel emissions are estimated to come from urbanized and industrialized areas but there are large uncertainties on these estimates that can be reduced with the help of atmospheric methods. I obtained the funding of the ANR CO2-MEGAPARIS project, which was the first project in Europe on urban CO2 emissions, with Paris as a testbed. Within that project, I collaborated with NASA JPL and CALTECH who were developing a similar project in Los Angeles. I developed a CO2 observing network in the Paris megacity and assess the role of natural and anthropogenic emissions on atmospheric CO2 in collaboration with the regional air quality agency AIRPARIF. I developed other programs on assessing thecorrelations between pollutants (VOCs, NOX, CO, aerosols) and CO2 in the Paris atmosphere to improve AIRPARIF emissions inventory. I also collaborated to CO2 modelling efforts with CNRM (Centre National de Recherches Météorologiques) and LSCE. In 2016, I obtained the funding of a new project called AMC funded byLabex OT-MED to adress the perturbation of anthropogenic emissions on the oceanic, terrestrial and atmospheric CO2 components in the Aix-Marseille area. I thus performed a long mission at MIO (Mediterranean Institute of Oceanography) in Marseille for about a year. I then obtained my transfer from OVSQ to OSU Institut Pytheas to continue this program and in 2018 I joined the PPM team at IMBE in Aix-en-Provence to start new programs on studying the perturbation of the natural atmosphere by anthropogenic activities in the Aix-Marseille urbanized and industrialized areas, in collaboration with the regional air quality agency ATMOSUD.

I am presently coordinating several research projects with an interdisciplinaring approach, among which the ANR COoL-AMmetropolis that aims at developing scenarios for mitigating atmospheric CO2 emissions in the Aix-Marseille-Provence metropolis area in collaboration with modelers (CNRM), environmental jurists (LIEU) and urbanists (IFSTTAR) and in link with the civil society and local stakeholders, in partnership with ATMOSUD and the GREC-SUD expert committee. I also coordinate research projects funded by the SUD-PACA region to better assess some key parameters of atmospheric dynamics that control the variability of atmospheric CO2 and CH4. I am also interested in better assessing the natural and anthropogenic sources of aerosols by remote sensing technics, as aerosols play a role on climate change that is still uncertain.

Within my mission of observation, I took the responsability of coordinating the atmospheric activities of the Observatoire de Haute Provence and I am developing scientific bridges between OHP-ICOS, O3HP and Fontblanche-ICOS sites thematics.

My teaching mission is national, and I coordinate a field training called SIMO each year at OHP for Master students from AMU and Paris area universities. I give lectures and practicals within the AMU Master 2 of Oceanography and Master 1 of Terrestrial and Environmental Sciences. I also contribute to the international doctoral school ERCA at OHP. I am part of the executive council of ITEM and Actris-Fr national infrasctrucure, and member of the scientific coucils of ATMOSUD and Parc National de Port-Cros.
