I am an Infectious Diseases physician-scientist with a research program in human immunology of malaria and clinical trials of immune modulatory interventions. Our group has been conducting detailed longitudinal cohort studies in children and pregnant women in order to study how repeated malaria shapes the cellular immune response. We are also studying how malaria control interventions such as antimalarial chemoprevention and vector control shape the acquisition and/or maintenance of protective immunity to malaria. We have expanded this work to not only include studying the mechanisms driving naturally acquired immunity to malaria, but other infectious diseases, including SARS CoV-2. We have also lead and/or participated in studies evaluating therapeutic strategies for patients with mild to moderate COVID-19.
