I received my Ph.D. in Molecular Chemistry from the Ecole Polytechnique (Palaiseau, France) in 2010 under the supervision of Julia Chamot-Rooke. During this time, I was involved in the development of a top-down mass spectrometry approach combined with hydrogen/deuterium exchange (HDX) for the structural analysis of protein complexes. After my PhD, I joined the proteomics core facility of the Institut Pasteur to work on the Orbitrap Velos ETD coupled with a liquid chromatography. I also manage the high-throughput bottom-up proteomics analysis. I divide my time between the core facility and the Structural Mass Spectrometry and Proteomics Unit headed by Julia Chamot-Rooke, where I am involved in the development of top-down proteomics using high resolution mass spectrometers (Orbitraps).
Cross-linking Mass Spectrometry
Covalent cross-linking combined to mass spectrometry is a powerful approach to address both the structure and composition of protein complexes. To improve the crucial stage of detection and characterization of cross-linked peptides, we have […]
Top-down strategies, based on the study of entire proteins, hold great promise for structural protein analysis. Whilst the classical, bottom-up approach can be useful for locating proteins already deposited in the databases, only a […]
Post translational modifications (PTM)
Post translational modifications (PTMs) are known to play pivotal roles in cellular physiology and disease, but only a few of the over 300 currently known modifications are extensively investigated in proteomic studies. The most […]
Affinity Purification Mass Spectrometry (AP-MS) is the method of choice to study protein-protein interactions (PPI) and complexes under near physiological conditions. A protein of interest – the bait – is purified by either a […]
ProteoCombiner is a high-performance software integrating shotgun with top-down proteomic data. The tool can deal with multiple experiments and search engines. It enables rapid and easy visualization, manual validation, and comparison of the identified […]
