About

I am working as a physicist scientist at the Laboratoire de Meteorologie Dynamique. I had my PhD in atmospheric pollution modeling from the Ecole Polytechnique in October 2009. My research interests include:

City-scale air quality modeling, subgrid scale parametrizations, spatial heterogeneity of emissions, urban meteorology
Air-quality and climate change interactions, air quality under changing conditions, adaptation to climate change
Human exposure modeling, indoor/outdoor air pollution transfer, population dynamics, hierarchical modeling, bayesian inference
Health impact assessment, exposure-response functions, time-series analysis
