CTPVSS Postdoc Rep

Caroline E. Moore, DVM, PhD

Postdoctoral Representative

Dr. Caroline Moore is the Steel Endowed Pathology Fellow in Disease Investigations at San Diego Zoo Global. In this role, she works as a veterinary toxicology researcher providing molecular and diagnostic toxicology support. She uses toxicology, pathology, molecular diagnostics, and epidemiology to better understand how environmental contaminates such as heavy metals, pesticides, and harmful algal blooms create roadblocks to wildlife conservation, and how to prevent them. Her current research is focused on how toxicants may cause multi- and transgenerational toxicity through epigenetic mutations, and if these epimutations can be biomarkers of health in wildlife.
