Research Summary
Michelle Cora, D.V.M., D.A.C.V.P., is a staff scientist and board certified clinical pathologist working in the Cellular and Molecular Pathogenesis Branch (CMPB) clinical pathology group in the Division of Translational Toxicology (DTT) at NIEHS. Cora is the principal clinical pathologist for the DTT, providing clinical pathology oversight and preparation for various National Toxicology Program (NTP) and NIEHS studies. Additionally, she provides clinical pathology collaborative and consultative support to investigators within the DTT and NIEHS. Cora has co-authored numerous publications, including over 40 NTP toxicology and technical reports regarding compounds studied by the NTP. In particular, she has led studies to evaluate the mechanism by which black cohosh extract induces a megaloblastic anemia in mice. She has also co-chaired several Society of Toxicologic Pathology committees, as well as served on the editorial board for the journal of Toxicologic Pathology.
Cora received her BS degree in biology and chemistry from Illinois College and, in 2000, her doctorate in veterinary medicine from the University of Illinois. After practicing small animal medicine in the Seattle area for 7 years, she began residency training in veterinary clinical pathology at North Carolina State University College of Veterinary Medicine. Upon completion of her residency training in 2010, Cora accepted a position as a research fellow in the CMPB Toxicologic Pathology Training Program; she subsequently joined the CMPB staff in 2013. In 2022, Cora took a position as a diagnostic clinical pathologist at Antech Diagnostics, returning to DTT as a staff scientist within CMPB in 2024. She has been a board certified clinical pathologist by the American College of Veterinary Pathologists since 2011.
