KEY WORDS
Pseudomonas aeruginosa,Francisella tularensis, Klebsiella pneumoniae, antibiotic resistence, toxins, host-pathogen interaction, regulation, signaling, nosocomial infection, anti-virulence
RESEARCH TOPICS
- P. aeruginosa virulence factors
* Type III secretion system – structure, function and inhibition
* Mechanisms of action of ExoU – intracellular trafficking
* Two partner secretion (TPS) proteins - ExlA and PdtA - P. aeruginosa regulatory networks
* two component systems involved in virulence and biofilms - Bacterial resistance to immune system – persistence mechanisms (Pseudomonas and Klebsiella)
- P. aeruginosa envelope
* Resistence to antimicrobial peptides (AMPs)
* Study of the elongasome / divisome - Virulence of Francisella tularensis
* Mechanisms of escape from the innate immune system
* Virulence factors : Type VI secretion system

SPECIFIC TECHNIQUES
- Bacterial genetics (engineering of KO mutants)
- Cellular bacteriology
- Genome-wide screens (CRISPR-Cas and Transposon)
- NGS (Tn-Seq, WGS, DAP-Seq, CHIP-Seq, RNA-Seq...)
- Microscopy (Fluorescence microscopy, IF, 3D video, confocal spinning-disk microscopy, automated microscopy and image analysis)
- Host-pathogen interaction (infection models eg : Galleria mellonella, macrophages, epithelial cells and human blood)
- Intaer-bacterial competition assay (E. coli, Pseudomonas sp, Acinetobacter, Bacillus sp…)
- FACS (cytokines measurements, detection and quantification of surface proteins, T3SS toxins injection test using beta-lactamase reporter system, sorting of cells and bacteria)
- Protein expression and purification (in E. coli and P. aeruginosa),
- Protein-protein and protein-lipid interactions, lipid raft purification
