Dr. Laurens is a pediatric infectious disease specialist with a primary research interest in malaria, typhoid fever, and other diseases that disproportionately affect people who live in resource-limited settings. He conducts studies at the Center for Vaccine Development (CVD) in Baltimore and at international sites in Burkina Faso, Mali, Malawi, and Uganda. Dr. Laurens evaluates vaccines and therapeutics that target infectious pathogens, studies the interaction of HIV and malaria and investigates the acquisition of antimalarial immunity. The broad goal of Dr. Laurens’ research is to illuminate the mechanisms of vaccine-induced immunity with the aim to inform development of vaccines and therapeutics.
