    Biography

    Jennifer M. Duringer holds the positions of Research Assistant Professor and Director of the Endophyte Service Laboratory at Oregon State University (Corvallis, OR, USA) in the Department of Environmental & Molecular Toxicology, College of Agricultural Sciences. She received her PhD in Toxicology from Oregon State University in 2003, as well as her BS in Zoology and BA in International Studies in 1998 before joining Oregon State University as a faculty researcher. Her research program focuses on food safety and examines the biochemical effects, mechanisms of toxicity and ultimate biotransformation of plant and fungal toxicants in humans and animals; investigates the potential of naturally produced fungal compounds in plant hosts to act as pest deterrents; delineates the molecular and chemical characterization of ecotypes of pathogenic fungi which has implications for disease management and safety; and determines the chemical profile and toxicological/therapeutic indices of essential oil extracts from native plants, with an emphasis on those consumed by indigenous populations throughout the world. Dr. Duringer also leads the testing program of the Endophyte Service Laboratory for endophyte mycotoxins in forages grown in the Pacific Northwest, United States that are destined for global distribution. She has authored over 30 peer-reviewed publications, mentors undergraduate and graduate students in research, and delivers lectures on toxicology and mycotoxins. She also performs outreach for STEM education and career days and participates as an active member of the Society of Toxicology, having held the positions of Councilor and four years in the Presidential chain for the Comparative and Veterinary Specialty Section.
