Research:
Environmental contaminant analysis and environmental toxicology.  Our laboratory conducts research into new analytical chemistry methods for the detection and quantification of environmental compounds of interest. In addition, we conduct research in nuclear magnetic resonance (NMR) structure elucidation of natural products and biomolecular compounds (i.e., proteins).

 

•    Nuclear magnetic resonance spectroscopy
•    NMR-based marine metabonomics
•    Environmental structural biology and natural products
