BACKGROUND

I am a native of Paris, France where I completed my Bachelor of Science and Master’s degree from Ecole Centrale. In 2018 I obtained a Master’s Degree at MIT. Having a solid background in applied mathematics and fluid mechanics, my interests lie in air-breathing propulsion, environmental modeling as well as numerical methods for engineering applications. During my spare time I play volleyball and frisbee as well as read books on math!

 

RESEARCH

The evaluation of the role of plume-scale processes on the long-term environmental impact of aviation. As a result, I developed an aircraft plume model, APCEMM, that is also able to model contrail formation and evolution.
GEOS-Chem is a state-of-the-art chemistry transport model driven by archived meteorology. One of my projects, funded by NCAR, consists of coupling GEOS-Chem to a global climate model, CESM, thus allowing GEOS-Chem to run with online meteorology and adding a new chemistry option to CESM.
The adjoint of GEOS-Chem allows to evaluate sensitivities of aggregated quantities (e.g. total ozone column) to emission quantities. However, the GEOS-Chem Adjoint had previously been limited to tropospheric processes. My research aims at introducing the Unified Chemistry eXtension (UCX), unifying both tropospheric and stratospheric representations, into the GEOS-Chem Adjoint. This enables us to evaluate the sensitivity of global quantities to both tropospheric and stratospheric forcing – including the effects of the next generation of supersonic aviation.
I also maintain the Aviation Emission Inventory Code (AEIC), which generates current or forecasts future emission datasets for the commercial aviation industry from existing flight schedules.
