Research Interests
Ethnobotany, Plant Ecology, Environmental History, Natural History of Remote Oceania, Human Impact on Hawaiian and other Tropical Pacific Islands

My research has focused on the cultural histories of human-plant interactions with special emphasis on the pan-global, traditional use of psychoactive species. I also study the human impact on native vegetation in tropical island ecosystems, both past and present, with a general interest in the natural history of Remote Oceania. My most important career object has been to contribute to and foster environmental education and preservation of traditional ecological and ethnobotanical knowledge.
