Funded PhD position in the field of lipid/protein interactions under High-Pressure NMR at ICSN Gif-sur-Yvette (Univ Paris-Saclay) and IBPC (Paris)

Dear all,

we are looking for a motivated PhD candidate in the field of structural biology by NMR to probe lipid/protein interactions under high hydrostatic pressure for a start in fall 2023 or earlier. The PhD is funded by a French ANR PhD fellowship.

The PhD student will be involved in a highly interdisciplinary research project at the frontiers of Chemistry, Biology and Physics. The aim is to continue the development of high-pressure NMR techniques to understand how membrane proteins affect lipid dynamics and how lipids affect protein dynamics in lipid bilayers.

PhD context and objective: Lipids and proteins are the main components of cell membranes. Although their mutual interactions and dynamics govern many cellular functions, we are still far from having a complete description. In our two CNRS laboratories (ICSN/IBPC), we have started to explore a new and original way to probe lipid/protein interactions within lipid bilayers using high hydrostatic pressure [1]. We will aim to demonstrate the existence of coupling between lipid and protein dynamics by NMR at high pressures (1 to 3000 bar) at various temperatures. We already identified strong lines of evidence of coupled motions but we will characterize at much higher details (timescales, …) the interactions by combining NMR relaxation data but also DLS, SAXS, fluorescence on different types of membrane proteins, including G protein-coupled receptors (GPCRs) and lipid bilayers systems. Notably, we will deeply analyze the lipid dynamics and phase transitions in nanometric particles.

The PhD student will be trained during the PhD thesis in the production and purification of isotopically enriched membrane proteins in nanodiscs (at IBPC), as well as in state-of-the-art NMR spectroscopy (ICSN) in two laboratories that are world experts in their fields. He/she will have privileged access to ICSN's exceptional NMR equipment (ten spectrometers up to 950 MHz including the High-Pressure setup, The two labs are closely located, with IBPC in Paris downtown (near Pantheon) and ICSN in the green area of Gif-sur-Yvette in Univ Paris-Saclay with a village spirit. Both labs are directly connected by the RER B train (~1h door to door), thus allowing to experience two radically different atmospheres. Complementary experiments will be collected at Soleil synchrotron (2km away from ICSN) in neighboring platforms at Paris-Saclay. In parallel, another PhD thesis will cover the molecular modelling aspect of the project under the supervision of J. Hénin/G. Stirnemann also at IBPC.

Required background: The candidate should ideally have a background in biochemistry, chemistry, physical-chemistry, biophysics, molecular biology and/or structural biology or a related discipline. A strong interest in structure-dynamics-interaction-function studies of proteins/lipids, in the physical-chemistry of biological systems and in collecting and analyzing data on biomolecular dynamics will be appreciated. Experience in protein expression and purification and/or NMR would be a plus.
