Dr. Harvell graduated from Clark Atlanta University with a B.S. and M.S. in Chemistry. She received a Ph.D. in Pathology and Microbiology from the University of Nebraska Medical Center while participating in the Cancer Research Training Program offered through the Eppley Institute for Research in Cancer and Allied Diseases. She joined the faculty of the University of Colorado Denver in 2007 after completing a postdoctoral fellowship in the laboratory of Dr. Kathryn Horwitz. As a postdoctoral fellow, Dr. Harvell developed an experimental in vivo model for studying mechanisms of estrogen and progesterone signaling in human breast cancers. She then translated that experimental work to the analysis of clinical tumors involving patients undergoing hormonal therapies for their breast cancers. Dr. Harvell is currently funded by a K12 award and is BIRCWH Scholar. Presently, she is investigating the role of hormones on tumor aggressiveness in pregnancy-associated breast cancer
