Research
Interests:
Most
of the research in my group is related to solving analytical problems
by analysis of complex samples. A primary tool is NMR spectroscopy
(both on solid and liquid samples), although other analytical methodologies
are also employed as needed. Applications include determining the
composition, microstructure, and morphology of copolymer systems
and applying chemometric techniques to spectroscopic data to accurately
determine the composition
of
complex mixtures such as pharmaceutical formulations.
Teaching
Interests:
Analytical
chemistry, general chemistry, and physical chemistry.
