A 2-year postdoc position is open at the Diversity Ecology and Evolution of Microbes DEEM team. Our laboratory is located in the new Saclay Campus of the University Paris-Saclay, ~30 km south of Paris. A suburban train connects the Campus to the city. We look for candidates to engage in a project with the following objectives: - Resolve the phylogenetic position of several unstable lineages in the tree of Archaea. - Study the evolution of gene content in the main archaeal groups.=20 - Identify horizontal gene transfer events that may have contributed to the adaptation of archaeal lineages to their environments. The genome sequences needed to address these questions are already available. The postdoc will be involved in their analysis using and developing different bioinformatics tools. Candidate profile: The candidates should be familiar with broad aspects of the diversity and evolution of archaea and have expertise in bioinformatics, in particular in molecular phylogeny and comparative genomics. Scripting abilities (e.g., Python, Perl, R=85) are necessary. Additional requirements: English proficiency (written and spoken); Good presentation and communication skills; Autonomy and organization; Synthetic mind and critical thinking. Application : Send your application (CV, cover letter and the name and contact information of at least two referees) to david.moreira@universite-paris-saclay.fr, puri.lopez@universite-paris-saclay.fr, and laura.eme@universite-paris-saclay.fr David Moreira (to subscribe/unsubscribe the EvolDir send mail to golding@mcmaster.ca)
