Danny Coyne has worked in tropical agriculture since 1989, beginning as a village extension office in rural Tanzania. He has spent most of his working life traversing Africa, working at both the national program and international research institute levels. With specialization in nematology, he is one of few nematologists in Africa. Of late he has broadened into the wider field of soil health in relation to plant host-pest-antagonist relations and the ecological aspects. Training underscores all of his work, whether at the farmer, technician, or academic level.
