Christopher E. Buddenhagen

Senior Scientist (Agricultural, veterinary and food sciences; Biological sciences; Environmental sciences)

Hamilton New Zealand

Chris Buddenhagen is a Senior Scientist at AgResearch in Ruakura, Hamilton, New Zealand. His research focuses on weed management, herbicide resistance, and biosecurity risk management. Chris has a strong background in conservation biology, specializing in biodiversity and invasive species management, with experience in New Zealand, the Galapagos, and Hawaii. He holds a PhD in evolutionary biology and plant systematics from Florida State University and completed a postdoctoral fellowship at the University of Florida, where he worked on plant epidemiology for roots, tubers, and bananas. Other areas of work: Prioritization and risk assessment, baseline information gathering, cost analysis for weed control, feasibility studies for eradication, problem description, and policy development, phylogenetics, science contract management, weed control methods and strategies, threat mitigation for rare species. His additional expertise includes herbarium curation and specimen digitization.
