Hillary Leigh Eaton

Dr. Eaton is the Department Chair of Biology and Chemistry and Associate Professor of Biology. She earned a Ph.D. from Oregon State University and has enjoyed a career as a research microbiologist in both academia and government agencies. She has over a decade of experience working in microbiology, pathology, toxicology and veterinary medicine, in addition to supporting the military through research focused in bioremediation, antimicrobial resistance, environmental and microbial forensics. Her research interests are in environmental forensics which include monitoring explosives used by the military and how the parent compounds and metabolites are bioremediated by the microbial populations in ecosystems; environmental DNA (eDNA) monitoring of different environments for microbial and vertebrate populations (applications in microbial and wildlife forensics) through metabarcoding and next-generation sequencing technologies.
