With my group, we are exploring the reactivity and role of organic compounds and organic radicals in aerobic systems such as Earth's atmosphere. For this, we develop new methods or new detection techniques and perform investigations in laboratory, ambient air, and other media. Most of our projects investigate the role of these compounds on the atmospheric oxidative capacity, air quality, and climate but the new techniques developped and information obtained on the reactions, in particular those involving free radicals, can be useful in other fields such as combustion or biochemistry. I have directed over 30 research projects on these topics so far, including large European projects such as the EU Excellence Chair VOCAT (pilot program for ERC grants) and the ERC advanced project EPHEMERAL.

CURRENT PROJECTS

1. ERC-Advanced Project EPHEMERAL

Organic peroxyl radicals ("RO2", where R is organic) are essential intermediates for the composition and oxidative capacity of Earth's atmosphere. Today,  there are no technique to observe them individually, leading to many unknowns in the understanding of their atmospheric cycles. Project EPHEMERAL focuses on developing chemical ionization (proton transfer) mass spectrometric techniques to observe and speciate these organic radicals in the atmosphere and in other complex mixtures.

2. Surfactants and cloud formation in Earth atmosphere
French (ANR)- Swiss (SNF) Project ORACLE

This project investigates the role of aerosols organic components on the formation of cloud droplets. The part in which we are invoved focuses on identifying and characterizing the surfactants present in atmospheric aerosols, and on studying their properties in laboratory.
