Our Research

The overall goal of our laboratory is to characterize the structure/function relationships of a variety of enzymatic catalysts at the atomic level. Much of this work is being extended into efforts to engineer novel structures and properties onto existing protein and enzyme scaffolds. A unifying theme between many of the individual projects is the selection and engineering of these enzymes for targeted therapeutic and/or biotech/industrical applications.

The tools employed by our lab are X-ray crystallography, computer modeling, and genetic manipulation of the molecules of interest, combined with biochemical analyses of function.
