Research Interests:

Our laboratory is developing a vaccine system that with only one immunization given at birth will protect from infectious diseases, as well as from asthma and allergies. Our laboratory uses state-of-the-art lab technology and bioinformatic approaches to get the most information out of the smallest samples. We are systematically dissecting the molecular mechanisms important in the human neonatal and infant response to infection or vaccination important for global health. Based on that knowledge, we are identifying immune modulators or vaccine adjuvants that help protect newborns from disease, and aid in their immune response to vaccines. This work is done in close collaboration with several large national and international research groups.
