Research Description

Research in the Horswill Laboratory centers around the bacterial pathogen Staphylococcus aureus. My studies have focused on the roles of the secreted enzyme hyaluronate lyase, encoded by the gene hysA, in S. aureus physiology and pathogenesis. Specifically, I am interested in how HysA is regulated, its overall contribution to S. aureus virulence and whether it is involved in various staphylococcal physiologic processes.
