Louis Picker graduated from UCLA with a B.S. in bacteriology in 1978 and took his M.D. degree at the University of California at San Francisco in 1982. After residency training in pathology at Beth Israel Hospital, Boston, and postdoctoral training in immunology at Stanford University Medical Center, he was appointed assistant professor and then associate professor of pathology at the University of Texas Southwestern Medical Center at Dallas. In 1999 he came to OHSU and ONPRC as professor of pathology/molecular microbiology and immunology in the OHSU School of Medicine and head of the Division of Pathobiology and Immunology.
