Research Interests
- My research interests are centered on the development of solid-state nuclear magnetic resonance (SSNMR), including magic-angle-spinning dynamic nuclear polarization (MAS-DNP) as tools for the characterization of atomic-scale structure and dynamics. I am particularly interested in the application of those tools for the characterization of surfaces and interfaces, including heterogeneous catalysts, and the interactions that molecules form at these interfaces.
