ResearchInterests

 

Interactions between Pollutants and Soil

                   I have been probing the interactions between soils and pollutants by solid-state NMR spectroscopy. These studies directly probe the interaction between pollutants and organic soil constituents and are directly relevant towards understanding the bioavailability and possible remediation methods of pollution.

 

Fundamental Aspects of Solid-State Nuclear Magnetic Resonance (NMR) Spectroscopy

            I am also interested in the fundamental aspects of solid-state NMR spectroscopy. These interests currently fall into three separate programs: developing a theoretical understanding of heteronuclear decoupling under fast magic angle spinning (MAS), understanding the effects of paramagnetic lanthanide metals on the solid-state NMR spectrum, and utilizing Bayesian statistics to analyze solid-state NMR spectra.
