He left active duty to receive advanced training in infectious diseases through a fellowship at the University of Virginia. During and after his clinical fellowship, he conducted a research fellowship on the role of bacterial protein toxins in the pathogenesis of anthrax, a disease he became interested in due to his experiences in the Navy.
