post doctoral position France

A joint post doctoral position (12 months) is available at the Commissariat de l'Energie Atomique (IRAMIS laboratory, CEA, Saclay, France – Dr. Dimitris Sakellariou) and Laboratoire de Chimie de la Matière Condensée de Paris (LCMCP - University P. et M. Curie, Paris, France – Pr. Christian Bonhomme).

START: september-october 2009

The title of the project is "NanoMACS" and deals with the study of nanomaterials [1] by the newly invented technique: "Magic Angle Coil Spinning" [2]. This project is funded by the CNano Ile de France consortium (see: http://www.cnanoidf.org/) and is a great challenge in terms of instrumentation / sensitivity in solid state NMR.

MACS is a straightforward approach to increase the NMR sensitivity and opens new opportunities for the study of small amount of samples (thin oxide films with nanometric thickness, small biosamples …). MACS will be developed at very high field (700 MHz), very fast MAS rotation (24 kHz), and for a large range of frequencies (1H, 31P, 27Al …). Double resonance experiments and homonuclear decoupling will be extended to MACS. Small samples containing expensive isotopes such as 43Ca, 29Si, 17O… will be studied by MACS.

All materials (including films) will be synthesized at the LCMCP (Paris), as well as the 700 MHz experiments. The instrumentation and experiments at 300 and 500 MHz will be performed at IRAMIS (Saclay).

This places us joint 14th out of all the 52 universities in this unit in the UK according to the Times Higher Education Supplement.

Further particulars of the studentship

Portable MRI scanner for security applications

This project will produce a non-invasive detection technique for dangerous substances (hazardous, flammable or explosive liquids) in sealed containers. Low cost and portable magnetic resonance will be used to measure the T1/T2 relaxation times and the effective self-diffusion coefficient of the hydrogenated molecules present in a liquid (or a soft solid) under investigation. These parameters together offer a 'fingerprint' that may be measured through both transparent and optically opaque sealed containers. By limiting the capability of the magnetic resonance hardware to just the measurements of these properties, extremely low cost and highly portable devices for security screening will be developed.

Post Doc - MicroMRI Applications in Neurobiology

Post Doctoral Position
MicroMRI Applications in Neurobiology
Biological Imaging Center
California Institute of Technology

Post Doctoral Position for Fall/Winter 2009. This position is aimed at development and application of high resolution MRI in small animal models of neurotransmitter dysfunction and neurodegenerative disease. The Biological Imaging Center and Caltech Brain Imaging Center (http://bioimaging.caltech.edu/) are highly interdisciplinary endeavors with biologists, chemists, physicists, and engineers working on a number of animal models of disease and developmental processes. We are interested in an individual who is firmly grounded in NMR theory and practice with an interest in applications in neurobiology. This work will involve various MR methodologies in rodent model systems; including fMRI, DTI and tract tracing with Mn2+ enhanced MRI, as well as simultaneous µMR/µPET imaging. Small animal MRI facilities at Caltech include a 11.7T/89mm scanner and a 7T/30cm scanner with µPET insert. There are also extensive facilities for all aspects of MRI hardware development and data analysis.

2 year post-doc in Orsay

Post-doctoral position in the Structural Biology team of Institut Curie/INSERMU759

The two-year post-doc program is dedicated to the study of internal dynamics of proteins in the microcrystalline form using dedicated NMR methods. In recent years it has become possible to determine protein structures in the solid state. In addition, recent observations suggest that internal dynamics may be also accessed in theses conditions. In particular, 15N spin relaxation rates have been measured in small proteins. This demonstrates the existence of motional processes on NMR time scales that are significantly longer that those accessible by liquid NMR.
The first NMR experiments will be done on the human protein centrin 2, and his C-terminal domain in complex with a target peptide (P17-XPC). In a second step other biologically relevant proteins will be studied. The candidate will endeavour to prepare the samples (protein expression, purification) and will participate to crystallization and NMR experiments. The structural and molecular characterization of studied proteins (structural changes, structural stability, interactions) in relation with the biological function will be done in our laboratory.
The post-doc project will be performed in close collaboration with partners from CEA Saclay and Ecole Normale Supérieure de Paris. Good knowledge in protein biochemistry (bacterial overproduction, purification), physicochemical analysis and NMR will be highly valued. The post-doctoral researcher will have the opportunity to participate to sample preparation and solid state dynamics NMR experiments. The post-doc position will be supported by a grant that has been awarded by the French Agence National de la Recherche (ANR).
