    - Characterizing translation-coupled RNA decay and protein quality control factors

    PI: Lionel BENARD ( Our team is investigating cellular processes that identify and degrade faulty mRNAs and their corresponding aberrant peptides, potentially toxic to cells. Ribosome-based quality controls have received much attention during the past decade, leading to the characterization of highly conserved surveillance effectors that rescue stalled ribosomes and degrade aberrant/damaged mRNAs and truncated peptides. Studies also suggest that alternative processes exist when these factors cannot operate, in stress conditions, in particular, involving mechanisms and factors of quality control that we aim to characterize, using S. cerevisiae as a model organism. The project combines yeast genetics, molecular biology and RNA biology, protein tagging, and immunoprecipitation including proteomics. We aim to determine the molecular composition of complexes critical in Ribosome Quality Control and define the roles of newly identified protein factors.

    Evaluation The position is designed as a first step in a research career, and the evaluation of candidates will be based primarily on their research qualifications and skills that can complement and strengthen ongoing research at the partner institutions. Step 1. The applications of each eligible candidate will be evaluated by independent international experts within the relevant research theme. Eligible candidates will be evaluated based on merit, motivation for the program, academic excellence, and personal qualifications such as collaboration and communication skills. Step 2. Up to three candidates will be selected for a video interview with the independent experts for each open position. After the interview, short-listed candidates will be invited to a remote conference with the project director and a DYNAMO board member to define the general scope of the project, training, and research environment. Applicants will be asked to write a 3-page project proposal, contributing their original ideas, and will have 2 weeks to submit it. Step 3. Each project proposal will be evaluated by one of the independent experts and the DYNAMO board member who evaluated the applicant in the previous steps. Final selection will be made based on the scores obtained in Steps 1, 2, and 3. The minimum score must be above 20/40. The best candidate will be offered the postdoctoral position with a start date of January 1 to April 30, 2023.

    The CNRS (Centre National de la Recherche Scientifique) is an equal opportunity employer. In addition, FP-DYNAMO-PARIS is committed to promoting the role of women in science and thus explicitly encourages them to apply.
