Description of Research Expertise

I have a special interest in Campylobacter and other gastrointestinal infections, with a focus on diagnostics, antibiotic resistance, and association of Campylobacter with Guillain-Barre Syndrome. My lab is also involved in several collaborative studies with Prof Lautenbach in the SOM, examining risk factors for development of antimicrobial resistant infections in hospitalized patients and in the community. Other areas of interest include diagnostic microbiology, molecular diagnostic microbiology, cost-effectiveness of laboratory testing.

Description of Clinical Expertise

I am currently Director of the Division of Laboratory Medicine at the Hospital of the University of Pennsylvania. I also am Associate Director of the Clinical Microbiology Laboratory. My areas of expertise include most areas of clinical microbiology. I have particular interests in the diagnosis of gastrointestinal infections.
