BIO: I obtained my Master's degree in planetary sciences from the University of Paris Sud, where I also worked at JPL with Bob Pappalardo on tidal stress modeling of Europa and surface fracture modeling.
I have (just) received my PhD in planetary sciences from the University of Paris Saclay. Did my PhD at the LATMOS lab in Paris (with Nathalie Carrasco) and Jet Propulsion Laboratory (with Murthy Gudipati), on Titan's atmospheric chemistry, where I analyzed the gas phase reactivity (neutral and ion species) of the ionosphere, and cloud condensation of the lower atmosphere, in the laboratory. I will be starting a postdoc at NASA Ames in a month, continuing work on Titan.

RESEARCH: I will be talking about Titan's atmosphere in light of some of the work I have been doing. In particular, I will give an overview of the photo-ionization and dissociation processes initiating a complex organic chemistry and haze formation in the upper atmosphere, and how neutral and ion chemistry are linked. Then, we will discuss what we know about the composition and photochemical evolution of that haze with the help of laboratory simulations. We can also discuss how our knowledge from Titan's complex atmospheric organic chemistry can help for understanding exoplanet atmospheres.
