His research interests have included the study of infections in the extremities of diabetic patients; investigations of antimicrobial agents in models that simulate closed space, neutropenic infections; the epidemiology of nosocomial pathogens (particularly MRSA, enterococci, and Clostridium difficile); the development and evaluation of new molecular diagnostic testing; measuring activity of new compounds against bacteria and fungi; and the study of the molecular mechanisms for the resistance of staphylococci and pneumococci to the new fluoroquinolone antimicrobial agents. Current research activities focus on using molecular testing methods to enhance infection control activities; understanding the regulation of antimicrobial agent resistance in enterococci, pneumococci, and staphylococci; designing new strategies for treatment of infections due to resistant bacteria; and developing new diagnostic tests for rapidly detecting microbial pathogens.
