Research Abstract:

I lead a multidisciplinary, clinical and translational research team focusing on Staphylococcus aureus, an aggressive pathogen causing a wide array of human disease. As I began my clinical Pediatric Infectious Diseases fellowship, it was quickly evident that community-associated methicillin-resistant S. aureus (CA-MRSA) infections in healthy children were emerging as a major public health challenge. Skin and soft tissue infections (SSTIs) comprise the majority of burden posed by CA-MRSA, resulting in lost time from school and work, pain, and subsequent scarring. Patients with invasive, life-threatening CA-MRSA infections underscore the severity of this problem, and inspire me to combat this scourge. Caring for these patients, I identified important deficits in our knowledge of CA-MRSA colonization and disease, treatment and prevention, microbial virulence mechanisms, and host defenses. To confront this major public health problem, I have developed an integrated research platform to define the clinical and molecular epidemiology of S. aureus colonization and infection, determine the effectiveness of strategies for treating and preventing S. aureus infections, and specify the bacterial and host mechanisms driving S. aureus transmission and disease.
