Research Interests

Our laboratory investigates the pathogenesis of the multidrug resistant gram-negative bacteria Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumonia. We focus on virulence factors such as the type III secretion, an apparatus that injects toxins directly into host cells. Other interests are the use of genomic approaches for the identification of novel virulence determinants and the development of novel translational approaches to treat bacterial infections. Our studies utilize a broad range of techniques, including molecular and cellular assays as well as animal models and epidemiologic studies on human populations.
