We use in-house data analysis and modeling tools to characterize immune responses to early-stage vaccine candidates in animal or in vitro infection models. Research areas include 1) antigen discovery and selection, 2) epitope mapping and antigen design, and 3) statistical analysis and modeling of immune assay data. We participate in a wide range of pre-clinical studies of vaccines for diseases, such as malaria, dengue fever, glanders, and Ebola infection.
