Summary of Work:

Our research focuses on understanding how disease-causing bacteria regulate gene expression in response to specific environmental conditions encountered within the infected host. Focus is placed on the study of RNA-mediated gene regulation that impact the ability of bacteria to survive within the host and cause disease.
