Andrew M. Hoffman, DVM, DVSc, Diplomate, ACVIM (PI)

hoffman-smDr. Andrew Hoffman, the Gilbert S. Kahn Dean of Veterinary Medicine at the University of Pennsylvania, is an acclaimed researcher, clinician, teacher, and mentor. Dr. Hoffman contributes extensively to veterinary research, teaching, and clinical care. His leadership of regenerative medicine and stem cell research programs resulted in important contributions to both animal and human health, demonstrating the profoundly positive impact of veterinary research. He regularly mentored faculty with an interest in clinical translational research and helped colleagues fully appreciate the career options available to them thanks to the versatile skills provided by a veterinary education.

While at Tufts University, Dr. Hoffman helped to build and lead the first outpatient pulmonary function testing laboratory for equine and canine patients in the world, which provided world-class care for animal patients while also making important contributions in developing animal models of human pulmonary disease.

The ongoing revolution in the treatment of severe human emphysema – increasing length and quality of life for patients and decreasing the morbidity and mortality of lung volume reduction treatment – traces in part to the work of Hoffman and his colleagues. An accomplished scholar and clinician, Dr. Hoffman served as director of the Tufts Regenerative Medicine Laboratory as well as the Stem Cell Laboratory. He led the Tufts Lung Function Laboratory for more than 20 years and also served for five years as director of the Tufts Equine Sports Medicine Program.

Dr. Hoffman is a Diplomate of the American College of Veterinary Internal Medicine, past president of the Veterinary Comparative Research Society, and a member of the International Society for Stem Cell Research. His research programs have received continuous funding from the National Institutes of Health for nearly 20 years. He has authored more than 100 publications, including many in leading scientific and clinical journals. Hoffman earned his undergraduate degree with honors in biology from the University of Delaware, received his veterinary degree from Cornell University, and holds a doctorate in veterinary science from the University of Guelph in Canada.

Rachel Derita, PhD, Director, EVC

DeRita-smThe Extracellular Vesicle Core Director, Rachel first received her B.S in Pre-Veterinary Medicine and Animal Biosciences at the University of Delaware and participated in distinguished research in avian genetics and transcriptomics.  She then received her doctorate at Thomas Jefferson University in Cancer Biology under Dr. Lucia Languino, where she studied the effects and contents of prostate cancer-derived EVs and identified a specific cell type within the tumor responsible for pro-tumor activity and distinguished herself as an expert in the EV field. She is published and cited within the EV field and is a frequently invited speaker at internationally attended conferences on the topic of EV biology.  She additionally has nearly a decade of education and multi-disciplinary leadership experience and aims to build bridges and encourage collaborations to distinguish and accelerate research at PennVet, UPenn and the greater Mid-Atlantic Region.
