Our group develops and applies transient techniques in solid-state nuclear magnetic resonance (SSNMR) to probe the chemical and physical properties of materials involved in heterogeneous catalysis, surface science and materials science. The work on catalysts focuses on studying the properties of surfaces, as well as the molecular structure, dynamics and reactions of the adsorbed species. Development of new SSNMR methods for these studies is the second major research area. Current efforts focus on homo- and hetero-nuclear correlation experiments for spin-1/2 and quadrupolar nuclei under vey fast magic angle spinning, and methods utilizing dynamic nuclear polarization (DNP).
