Our group studies the immunological, hormonal, and genetic factors mediating sex differences, age-related changes, and the effects of pregnancy on infectious disease pathogenesis and vaccination. Using several model systems, including influenza, Zika, and malaria, we are uncovering the mechanisms mediating how females have higher inflammatory and adaptive immune responses than males as well as how immune responses to infection or vaccination change during pregnancy and over the life course.
