My current research focuses on the design and conduct of Phase I and 2 clinical vaccine trials and challenge studies, especially for Enteric diseases and Influenza. I have served as the Principal Investigator for phase I and II clinical trials for a variety of vaccines -- including influenza (pandemic and seasonal), malaria, Enterotoxigenic E. coli (ETEC), Shigella and Ebola. In addition, I have been a co-investigator on pediatric and adult vaccine trials for dengue and respiratory viruses as well as a human metapneumovirus challenge study. Safety is an integral part of all of my vaccine trials. With training in the Clinical Parasitology Service at the NIH as a fellow, I now attend in the Geographic Medicine Center at Johns Hopkins University, as well as on the Infectious Disease Consult Service.
