Diana   Scorpio DVM, MPH, DACLAM

Adjunct Professor

Dr. Scorpio is active in many professional organizations, including AALAS and ACLAM.  She has published in laboratory animal journals and has presented her work at AALAS National Meetings and ACLAM Forum on numerous laboratory animal medicine topics.  She continues to collaborate with investigators at Johns Hopkins University, University of Maryland, and at several other biomedical institutions. She has recently expanded her research interests to the global health arena, with infectious disease research performed in collaboration with institutions in Brazil, Italy, and now will continue her work in St. Kitts. 

Dr. Scorpio was Assistant Professor in the Department of Molecular and Comparative Pathobiology and Director of Large Animal Medicine for Research Animal Resources.  She spent the next several years at the University of California, Davis National Primate Research Center as Head of Primate Medicine and Surgery, and the National University of Singapore as Head of Veterinary Services.
