Unambiguous identification of individual metabolites (small molecules) present in complex biofluids such as urine, blood serum or culture media constitutes a crucial prerequisite for quantitative metabolomics, towards better understanding of biochemical processes in living systems. The proposed project will develop new approaches based on projection spectroscopy for fast multidimensional NMR correlation, and the combined use of novel algorithms for efficient metabolite identification. Association of separation methods for sample preparation will also be investigated to increase the observable dynamic range in solution. Background: The candidate should optimally have a strong background in physical chemistry or chemistry. Additional knowledge of scientific programming would be a plus, but is not required.
