Research Interests

Dr. Chu's research is focused on maternal immunization, in particular vaccines against influenza and respiratory syncytial virus (RSV). She studies the virologic and immunologic correlates of protection from respiratory viral infections in pregnant women, infants, and older adults, and performs clinical trials of vaccine candidates in both domestic and international sites, including Nepal and Bangladesh. She has developed immunologic assays to study transplacental transfer and decay kinetics of RSV antibody, and nosocomial and household transmission of respiratory viruses by genotypic analysis and molecular sequencing.
