Postdoc France

The biomolecular NMR research group of Dr. Eric Guittet ( at the Institut de Chimie des Substances Naturelles in Gif-sur-Yvette, suburb of Paris (France), is looking to recruit Master students, PhD students and postdocs from all nationalities.

Our laboratory uses modern NMR techniques to decipher the molecular mechanisms underlying biological functions for a variety of systems involving proteins such as enzymes, unfolded proteins and macromolecular complexes. We are also interested in structure-based drug design and in developing new methodology for protein NMR resonance assignment and dynamic studies of slow motions in proteins.

We are seeking candidates for the following projects:

- Investigation of the catalytic role of interdomain motion in a 60kDa enzyme. (PI Ewen Lescop)
- Analysis of the interactions of WH2/Tbeta domains with actin, investigation of their functions in the regulation of actin polymerization. (PI Carine van Heijenoort)
- Investigation of membrane proteins. (PI Eric Guittet)
- Fragment-based drug design, including methological developments. (PI Eric Guittet)
- Solid-state NMR characterization of amyloid fibrils (PI Christina Sizun)

Our laboratory offers access to several high field liquid state NMR spectrometers, including a 950 MHz, a 800MHz and two 600MHz spectrometers equipped with cryoprobes, as well as a 700MHz for dual liquid and solid-state NMR use. Our institute (ICSN) is located on the CNRS campus of Gif-sur-Yvette, a charming village with countryside flavour, 40mn away from Paris by train. The campus, which is mainly dedicated to life sciences, is part of the large scientific community located South-West of Paris, next to the Soleil synchrotron and Paris XI-Orsay University.

Highly motivated applicants with a strong background in biochemistry, biophysics and/or NMR spectroscopy are invited to apply. Please contact for more information and include a CV with a summary of research interests and accomplishments.
