The Gaw Lab studies infectious diseases in pregnancy. Leveraging prospectively collected pregnancy specimens, we study how maternal-fetal immune responses adapt over gestation. We also study how inflammation impacts placental function and pregnancy outcomes, such as fetal growth restriction. Diseases of interest include malaria, COVID-19, and syphilis.
