George S. Bloom, Ph.D.

Professor of Biology, Cell Biology, and Neuroscience, University of Virginia


Dr. Bloom obtained his Bachelor of Arts degree from the University of Pennsylvania in 1973 and his Ph.D. from the University of Pennsylvania in 1979. He then completed two postdoctoral fellowships: from 1979–1980 at the University of North Carolina’s Cancer Research Center, and from 1980–1984 at the Worcester Foundation for Experimental Biology, where his longstanding interest in neuronal cell biology was initiated in the laboratory of Dr. Richard Vallee. After finishing his postdoctoral training in 1984, Dr. Bloom joined the faculty of the Department of Cell Biology at the University of Texas Southwestern Medical Center, where he remained until his move to the University of Virginia in 2000.
