28 mag 2024

An Open Position for a post-doc in France.

The position: Post-doc in structural Biology/Astrobiology.

Institut de Biologie Structurale UMR 5075- Grenoble- France

The project A 18 Months post-doc position is available in the ELMA team at the Institut de Biologie Structurale in Grenoble, France. As part of a project funded by the "origin of Life" program of the University of Grenoble Alpes ( to:

  • Understand the molecular basis of extremophilic adaptation at the

    proteome scale.

  • Establish a framework for the search for traces of extraterrestrial life,

    particularly in samples from Martian brines.

    The effects of harsh conditions (salts, temperatures, pressure) on purified proteomes from different types of extremophilic organisms will be assessed using nano-DSF, nano-photometry and neutron diffusion assays. Based on these experiments affinity chromatography trapping and MS/MS proteomics analyses combined with structure predictions (AlphaFold 2) will allow to identify the most robust and fragile protein populations vis-à-vis different physicochemical stresses.

Your profile We are looking for a highly motivated, team-oriented individual with a PhD in structural biology/biophysics or protein biochemistry. An additional expertise in proteomic analysis and bioinformatics is desirable. The candidate must be interested in basic research related to environmental adaptation and exobiology.

Work environment The IBS is a research unit, affiliated to the University Grenoble-Alpes, the CNRS and the CEA. It currently employs 280 people, including many students and post-docs from different countries. It has high-performance and internationally competitive facilities in biophysics and structural biology. The Institute is a founding member of the Partnership for Structural Biology with prestigious pan-European institutes: the European X- ray synchrotron source, the European neutron scattering center, the Grenoble station of EMBL, all located nearby and offering a strong international environment. Under the authority of B. Franzetti, the ELMA specializes in study of molecular and cellular adaptations that allow microorganisms to colonize extreme environments (salt lakes, abysses, hydrothermal springs, etc). website:
