Research Activities

My main research interests are resistance to antimicrobial agents among Gram-negative bacteria especially the laboratory detection, characterization, molecular epidemiology and evolution of bacteria with newer b-lactamases such as AmpC, Extended-spectrum b-lactamases and Carbapenemases. I have also been involved in population-based studies and the role of high-risk clones and mobile genetic elements (such as plasmids) among bacteria producing these newer types of b-lactamases.
