Research in my laboratory is focused on the elucidation of the structure and catalytic mechanism of enzymes. A summary of ongoing investigations in our laboratory is summarized on the research group page of our laboratory wiki. The laboratory wiki also contains two research resource guides in protein engineering and in protein X-ray crystallography, two techniques our laboratory uses extensively. Please consult these resources for additional details.


BS (Biochemistry), University of Alabama, 1976; PhD (Chemistry), University of Alabama, 1981


Biophysical chemistry: enzyme kinetics, X-ray crystallography, protein engineering


Teaching interests: biochemistry, analytical chemistry, general chemistry

Research interests: enzymology, the isolation, purification, and characterization of enzymes, especially experimental kinetics; protein engineering, the specific alteration of enzyme structure using recombinant DNA methods; X-ray crystallography, the determination of three-dimensional protein structures from X-ray diffraction by single protein crystals.
