研究领域

The main focus of my research is to study cerebral energy metabolism and its relationship to functional activation in human and animal brain. NMR spectroscopy (proton, (inverse) carbon-13 and phosphorus-31) is the most important tool to study metabolic processes and fluxes non-invasively in vivo. Besides studying brain energy metabolism, a significant part of the research is reserved for technological and methodological improvements to the technique of NMR spectroscopy. These include methods for better water suppression, spatial localization, spectral editing, quantification and shimming.
