PhDs & Postdocs in MAS-DNP at CEA Grenoble (France)

Contact Gaël De Paëpe (gael.depaepe@cea.fr)

PhD and Postdoc positions are now available at CEA-INAC (twinned with the Univ. Grenoble Alpes), France. The ERC-funded project will focus on the further development of an emerging hyperpolarization technique called MAS-DNP (Magic Angle Spinning Dynamic Nuclear Polarization). Combining hardware development, computational/theoretical approaches and sophisticated NMR experiments, we will apply the newly developed methodology to improve the understanding of challenging systems (both materials and biomolecules).

Line of research / welcomed fields of expertize:

– Designing and conducting advanced DNP/NMR experiments

– Spin dynamics simulations for pulse sequence development

– Hardware development for cryogenic helium spinning

– RF/MW engineering

– Quantum Chemical Calculations and Molecular Dynamics simulations

– Experience with material and/or biomolecular sample preparation

– Basic knowledge in radical chemistry

– Matlab programming

– EPR experiments

The funded project is part of a larger ongoing activity involving a strong partnership between our lab and LNCMI/CNRS (for high-field EPR) as well as an industrial partner (Bruker Biospin). Motivated candidates must have a good command (written / spoken) of English and should send a detailed CV and a letter of motivation, as well as any questions, to gael.depaepe@cea.fr.

Grenoble is one of the major cities in Europe for research with a large international scientific community. In addition, Grenoble has a large international student population, is a very pleasant city to live in, and is known as the “Capital of the Alps” with easy access to great skiing and hiking. It’s also only 2 hours’ drive to the Mediterranean Sea, Italy, or Switzerland. Grenoble, Lyon, and Geneva airports are nearby and permit straightforward international travel.
