Areas of Interest:

  • Streptococcus pneumoniae (pneumococcus) is an important human pathogen causing more than 1 million deaths each year worldwide. A critical first step in pneumococcal pathogenesis is colonization of the airway. However, the mechanisms by which this important human pathogen establishes and maintains colonization is poorly understood. S. pneumoniae has the ability to manipulate host sugars. We hypothesize that bacterial deglycosylation of human targets may contribute to colonization and therefore pathogenesis. We are working to define ability of S. pneumoniae to modify host carbohydrates and the contribution of that to modification to pathogenesis. The long-term aims of my research are to understand how pneumococci efficiently colonize humans in order to design more efficient vaccines or therapeutics.
