Current research projects are on Group B Streptococcus are focused toward understanding how the pathogen migrates through different host niches during infections. These include identifying the environmental cues/signals that are sensed by the pathogen for regulation of toxins and other virulence factors. Our studies on S. aureusare focused on elucidating on factors that regulate antibiotic resistance and virulence of the pathogen. We are also investigating how mutations in host signaling pathways affect disease susceptibility to S. aureus. This is particularly relevant as patients with genetic disorders such as Jobs syndrome and chronic granulomatous disease (CGD) are prone to recurrent and life-threatening infections due to S. aureus.
