My main research interest is to understand the roles of the biosphere and of various human activities on the carbon cycle using data assimilation techniques. By combining atmospheric greenhouse gas measurements and numerical weather models, I collect information on the exchanges of carbon from land and coastal surfaces to the atmosphere. I am particularly interested in satellite measurements and dense network of ground-based sensors to characterize carbon sources from large metropolitan areas or sinks from natural and agrilcutural landscapes.

Current research projects:

ACT-America (aircraft campaigns over North America)

INFLUX experiment (urban-scale emissions of greenhouse gases)

NASA OCO-3 (satellite mission on fossil fuel emissions)

MERCI-CO2 (urban emissions of CO2 in Mexico City)
