Research Interest

Staphylococcus aureus infect every niche of the human host, is the leading cause of Gram-positive sepsis, and causes over 900,000 severe infections annually in the United States. Additionally, 10 % of S. aureus infections are caused by stains resistant to commonly used antibiotics. Our lab furthers the knowledge of how the host kills S. aureus and how S. aureus avoids killing by the host. Specifically, we are focused on the role of protein post-translational modifications at the host-pathogen interface. Through multiple projects that use aspects of analytical chemistry, bacteriology, bacterial pathogenesis, and chemical biology, both in vitro and in vivo, we seek to identify and validate S. aureus therapeutic weaknesses for targeting by the next generation of antimicrobials.
