We are looking for a postdoctoral researcher interested in the relation between the chromosome structure and expression in the context of bacterial pathogenicity. He/she will work within the CAGE project funded by the ANR in the team Chromatin and Regulation of Bacterial Pathogenicity of the MAP laboratory( The objective is to characterize the chromosome dynamics of the phytopathogen Dickeya dadantii under stress conditions and during plant infection using Hi-C and ChIP-Seq together with transcriptomics, in order to unveil novel mechanisms of virulence regulation, with a particular focus on the activity of Nucleoid Associated Proteins (NAPs) and DNA supercoiling. 



- Rigor and autonomy
- Experience in bacterial genetics, microscopy, RNA-Seq, ChIP-Seq, or Hi-C (in bacteria or eukaryotes).

- Experience in Next Generation Sequencing analysis (Python language, UNIX environment is preferred; training can be taken).
- Ability to work as a team and be a team player
- Assemble experimental results and ability to present his/her work orally and in writing
- Good English skills 


Work Context

The postdoc will have the opportunity to work in an internationally recognized team in the field of regulation of bacterial virulence in relation to chromosome structure. He/she will develop autonomous research under the supervision of the coordinator of the project, and will benefit of the collaboration with other team members for experimental design and computational analysis and modeling. All equipments needed for the project are available in the host Institute.

The postdoc will also work in close collaboration with Axel Cournac in the group of Romain Koszul, Pasteur Institute, team Spatial Regulation of Genomes, CNRS UMR3525

The MAP UMR5240 is a University of Lyon I/INSA-Lyon/CNRS research unit located in the research campus of La Doua (Lyon). The campus is in close proximity to a natural park and is deserved by public transportation with direct access to Lyon city center. The institute hosts around 70 people among 5 research teams and benefits from state-of-the-art technical facilities of FR BioEEnvis
