Dr. Sandra J.Ewald is a professor in the Department of Pathobiology with a joint appointment in the Department of Poultry Science. She earned the B.A. degree in biology at the University of Texas at Austin in 1970 and the Ph.D. degree in Zoology (Immunogenetics) from the same institution in 1976. She was a postdoctoral fellow at the California Institute of Technology. She served on the faculty of the Department of Microbiology at Montana State University from 1979 to 1990, when she joined the faculty at Auburn .
 

Research Interests

Recent studies focus on molecular characterization of genes of the chicken major histocompatibility complex (MHC).  The MHC influences resistance to a number of infectious diseases in chickens.  We are presently examining immunological mechanisms of resistance to disease.
