I have been the manager of the Pasteur Proteomics facility since September 2013. I am responsible for the operations of the proteomics platform and the coordination of the different ongoing projects. I did my PhD research in the group of Dr. Bernard Monsarrat and Dr. Odile Schiltz at the Institute of Pharmacology and Structural Biology (IPBS, University Paul Sabatier, UPS, also known as Toulouse III, France). As part of my PhD work, I used high-resolution mass spectrometers, including the LTQ-Orbitrap, in combination with various quantitative proteomic approaches. My focus was on stable isotope labelling strategies (SILAC and ICAT) to study the proteasome inhibitor effect in acute myeloid leukaemia cells. I then moved to the Institute of Molecular Systems Biology in Eidgenössische Technische Hochschule (ETH Zürich) as a post-doctoral fellow in the group of Professor Ruedi Aebersold. I worked on multiple projects using mass spectrometry to assess changes in protein abundance and posttranslational modifications, e.g., ubiquitin, SUMO, and chlorination of proteins using discovery-driven and targeted mass spectrometry. During this time, I utilised the new data independent acquisition mode developed in Ruedi Aebersold Lab, namely SWATH-MS.
Insights into amebiasis using a human 3D-intestinal model (ANR-14-IFEC-0001-02)
This project is a part of the international Infect-Era program, AMOEBAC: Entamoeba histolytica-bacterium interaction and the role of this interaction in intestinal pathogenesis (http://www.infect-era.eu/2nd-call-2014) The aim of this investigation is to understand the induced […]
EPIC-XS: European Proteomics Infrastructure Consortium providing access
The European Proteomics Infrastructure Consortium providing access (EPIC-XS) consists of a unified network of experienced access providers and research groups who share a common goal; to facilitate the development and sustainability of proteomics exploration […]
Landscape of protein ubiquitylation during infection by CNF1-producing uropathogenic E. coli
CNF1 is a toxin that catalyzes the permanent activation of host RhoA, Rac1 and Cdc42 small GTPases by selective deamidation of a glutamine residue into a glutamic acid. This 1 dalton post-translational modification can […]
Role of tubulin glutamylation in flagellum construction (TUBGLUFLA)
Cilia and flagella are essential eukaryotic organelles composed of an evolutionary conserved structure of 9 doublet microtubules that are similar but not equivalent. We propose that a tubulin post-translational modification called glutamylation could act […]
Acyl-CoAs are the major metabolic carriers of carbon in living organisms. The most conserved ways to their synthesis include the oxidative decarboxylation of α-ketoacids carried out by three distinct enzymatic machineries: the pyruvate dehydrogenase […]
PTR 539 – A multilevel systems approach to elucidate the host-Leishmania interactome and to identify host targets for anti-leishmanial drug discovery
Our PTR project investigates at the complex interface between the intracellular pathogen Leishmania and its macrophage host cell. We will apply systems-wide analyses to elucidate the molecular mechanisms underlying the reciprocal metabolic relationship between […]
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 […]
Single Cell Proteomics
Successful extension of mass spectrometry-based (MS) proteomics to single cells is very challenging, mainly due to low analysis throughput and insufficient proteome coverage in single cells. To address these challenges, new pipelines have emerged […]
