Research Interests:

Protein structure and function studies on bacterial enzymes responsible for antibiotic resistance. These enzymes include beta-lactamases which catalyze the hydrolysis of penicillins and cephalosporins as well as a transpeptidase enzyme (PBP2a) from the bacterial pathogen Staphylococcus aureus which provides resistance to virtually all beta-lactam antibiotics.

Functional genomics studies on Treponema pallidum, the causative agent of syphilis. High-throughput techniques have been used to clone >95% of the open reading frames of this organism into protein expression vectors as well as vectors for phage display and two-hybrid analysis. These gene sets are being used to identify important antigens during T. pallidum infections and to map protein-protein interactions on the surface of the organism.
