Research Focus

Our laboratory is interested in the molecular mechanisms of antibiotic resistance, both chromosomal and plasmid-mediated, in Gram-negative pathogens such as Escherichia coli, Klebsiella pneumoniae, Salmonella spp., and Pseudomonas aeruginosa. We are especially interested in mechanisms involved in the regulation of gene expression required for the expression of plasmid-encoded resistance genes and how chromosomal encoded factors play a role in the expression of those genes.  Our laboratory also evaluates mechanisms involved in the emergence of P. aeruginosa resistance associated with cystic fibrosis patients. Another area of active research involves the development of PCR-based techniques for the molecular detection of genes encoding extended-spectrum beta-lactamases, plasmid-mediated AmpC beta-lactamases, and carbapenemases in clinical isolates.
