Dr Jonathan Lundgren is an agroecologist and entomologist who left a job with the US Department of Agriculture in 2015 after filing a whistleblower suit, alleging the agency had suppressed his research on bee health and pesticides. He is now director of the Ecdysis Foundation for research into regenerative agriculture, and chief executive of Blue Dasher Farm in South Dakota, where he focuses on reforming food production systems along ecological principals - promoting soil health and biodiversity - while running a profitable farm. He received his PhD in Entomology from the University of Illinois in 2004 and was a professional pesticide evaluator with USDA for 11 years. He received the Presidential Early Career Award for Science and Engineering from Barack Obama. Lundgren says that insecticides are an addiction - the more you use, the more you need. His is in Aotearoa next week for a workshop on Conservation Biological Control of Invertebrate Pests, hosted by the Bio-Protection Research Centre.
