Research outline(1-3 pages)

  Streptococcus pyogenes (group A Streptococcus, GAS) is the major human pathogen causes various diseases including pharyngitis, cellulitis, scarlet fever, necrotizing fasciitis, and toxic shock syndrome. Although this pathogen is sensitive to antibiotics treatment, it still causes more than 500,000 deaths per year in the global scale. In addition, no vaccine is available for preventing GAS infections. My research focuses on studying the mechanism of GAS virulence genes regulation under stress conditions, and the biological significance of GAS phenotypic heterogeneity and instability.
