Dr. Dawid’s research interests involve understanding the bacterial factors that allow respiratory pathogens to survive and transmit between humans. Her work specifically focuses on the important pediatric pathogen, Streptococcus pneumoniae. This organism is capable of causing a range of infections from ear and sinus infections to pneumonia and meningitis. Although a highly effective vaccine has been in use for several years, the adaptive nature of this organism has allowed it to change its surface properties and escape some of the protection provided by the vaccine. We are interested in determining the mechanism of this adaptation in order to better predict the changes in the bacterial population in response to vaccination.


Dr. Dawid has been a member of the Pediatric Infectious Diseases Faculty since 2008 and holds a joint appointment in the Department of Microbiology and Immunology. She is a member of the Infectious Diseases Society of America, the American Society for Microbiology and the Pediatric Infectious Diseases Society.
