After a PhD in informatics on graph analysis (metabolic networks and sRNA-mRNA interaction graphs) at the LaBRI (Université de Bordeaux), I joined the DSIMB team (INTS) for a post-doc on structural modeling. Then, I performed a second post-doc at Metagenopolis – INRA Jouy-en-Josas, where I was initiated to the analysis of metagenomic data. I was recruited at the HUB in 2015, and since I pursue the development of methods dedicated to the treatment of metagenomic data by combining either the treatment of sequencing data, the statistics, the protein structural modeling and the graph analysis.

Graduated in “Structural Genomics and Bioinformatics”, I mainly worked during almost 6 years at the Genoscope (CEA) in the LABGeM team, within the microbial annotation platform MicroScope. I specifically focused on functional annotation and microbial metabolic pathways prediction and reconstruction, through pipeline implementation, database modeling and web interface development. Broadly, interactions in the MicroScope platform allowed me to tackle the whole annotation process: from genome assembly and gene prediction to network reconstruction. I also performed several comparative genomics analyses. As a member of the “Hub team”, I now take part to various projects, linked to HTS data, on different subjects (lncRNAs and stem cells, HIV integration and DNA structure, Ribosomal protein genes and genome evolution, Natural Antisense Transcripts in compact genomes…).

The microbiota of the gastrointestinal tract is a diverse mixture different species and strains of bacteria. We aim to identify regions of dissimilarity between two different bacterial strains to be able to quantitate their relative abundance and thus obtain information about their ability to cohabitate a common environment. In addition, we are interested in assessing the surface localised protein repertoir of specific species through a combination bioinformatic analysis and proteomics.
Looking for DNMT (DNA methyltransferase) orthologs in Leishmania which could be potential targets of epigenetic inhibitors active against the parasite.
Séquençage à haut débit (NGS) et traitement de séquences ADN des domaines variables d’anticorps simple chaine d’alpaga (domaines VHH ou Nanobodies®)
Dans notre laboratoire nous nous intéressons à la conception et construction de banques d’anticorps simple chaine issus du répertoire immunitaire des alpagas. Ces banques immunes, sont constituées d’un million de séquences ADN différentes codant pour les domaines variables des anticorps simple chaine spécifiques d’une protéine cible donnée, plus communément appelés domaines VHH ou Nanobodies®. Nous souhaitons à présent caractériser ces banques crées au laboratoire par séquençage ADN à haut débit (NGS Séquence MiSeq). Cette méthode conduit à la création de fichiers composés de millions de séquences ADN nécessitant d’être traitées et analysées par la suite.
We tested DNMT and RNMT inhibitors on Leishmania parasites survival and would like to know which could be the potential targets.
Describing viruses of invertebrate vectors of disease, provides better understanding of evolution and host range for various virus groups. In addition to filling the gaps in the current knowledge of the virosphere, viromes can serve as necessary contextual data for ongoing disease control measures and outbreak preparedness. This project aims at delivering a comprehensive analysis of RNA viromes from RNA sequencing data.
Finely tuned sensory systems enable bacteria to sense and respond to fluctuating environments, coordinating adaptive changes in metabolic pathways and physiological outputs. For pathogenic Leptospira, signaling pathways allow a timely expression of virulence factors during the successive steps of infection of a mammal host. As the bacteria is excreted by its host, signaling pathways enable switching the expression towards factors promoting survival in the environment. A unifying theme across bacterial species is that biofilm formation coincides with the synthesis of the cellular signaling molecule bis-(3?-5?)-cyclic dimeric guanosine monophosphate (c-di-GMP) and this feature seems to be conserved in Leptospira. Our current work shows that the c-di-GMP regulation pathway is a major regulatory network involved in biofilm formation, virulence and motility in the pathogen Leptospira interrogans. Biofilm production and virulence expression is quite variable across the leptospira genus (highly virulent species, low virulent species and saprophytes species showing increase biofilm production). We would like to explore how the c-di-GMP metabolism, and the many genes associated with its synthesis, and degradation have evolved across the leptospira genus. We believe that understanding the evolutionary relationship of the c-di-GMP metabolism genes in the Leptospira genus would help us to understand the contribution of this second messenger to pathogenesis and biofilm formation in the Leptospira genus
