研究领域

The primary focus of my research is the development and application of techniques for the acquisition of high quality solid-state NMR (SSNMR) spectra of nuclides across the periodic table - in particular, we focus on designing pulse sequences for efficient acquisition of ultra-wideline NMR spectra. There are innumerable materials that can be better understood via characterization of structure and dynamics at the molecular level via multinuclear SSNMR techniques. X-ray diffraction (single-crystal and powder) and first principles calculations of NMR interaction tensors are used along side of SSNMR experiments to develop correlations between NMR parameters and structure, symmetry and dynamics. These methodologies have found widespread application in the study of traditional small and medium sized molecules in organic, inorganic, biological and organometallic chemistry, as well as inorganic materials, pharmaceuticals, heterogeneous catalysts and associated support materials, polymers, biomolecules, surfaces and nanoparticles.
