Dr. Smith earned his B.A. from the University of California at Berkeley in pre-medical sciences and anthropology and his M.D. from the University of Rochester, N.Y. After residency in internal medicine at Vanderbilt and a fellowship in gastroenterology at the University of Colorado, which included training in clinical parasitology at the University of Natal in Durban, S. Africa, he did a postdoctoral fellowship in parasite immunology in the Laboratory of Parasitic Diseases, NIAID, NIH and then joined the Laboratory of Cellular Immunology, NIDCR, NIH, where he was a Senior Investigator until joining the UAB Department of Medicine in 1993. Dr. Smith is currently a Professor and the Director of theMucosal HIV and Immunobiology Center (MHIC) at UAB.
