In the context of an ERC-funded project, we developed a longitudinal cohort to study the evolution of commensal Escherichia coli. We are looking for a postdoctoral researcher to analyze 500+ genomes isolated at several timepoints from 50 healthy volunteers to unravel the bacterial genetic determinants of colonization dynamics. E. coli is a major pathogen but little is known of its commensal lifestyle; this project represents a unique opportunity to make progress on these questions.
