Research Interests

I study antibiotic resistant bacteria with a focus on their transmission or spread. Because of the need to develop nursing home-specific infection control polices and the longer length of stay in this setting, I partner with nursing homes. Our research studies have been translated into practice through new CDC guidance as Enhanced Barrier Precautions (EBP) for emerging MDROs such as pan-resistant bacteria. In the future, the CDC may recommend EBP for all residents with skin breakdown and medical devices in nursing homes moving away from the focus on culture-based precautions.

More recently I have focused on diabetic foot infection, a common cause of amputation in people with diabetes. We are completing recruitment for a randomized double-blinded clinical trial of a topical antiseptic agent for foot hygiene in high-risk Veterans to test whether we can prevent diabetic foot ulcers and their associated infections. I am proud of our research program strives to develop sustainable and reproducible ways to improve the outcomes and quality of life of people at risk for antibiotic resistant infections.
