Clinical Vaccine Research

Vaccine clinical trials often generate a large number of immune measures at multiple time points. By using data from such trials, we develop new computational methods to carry out 1) univariate and correlation analyses, 2) multivariate analysis, and 3) mathematical modeling to identify potential correlates of protection or mechanisms of action in vaccine studies. We work closely with clinical collaborators on a range of infectious diseases, including malaria and dengue fever.
