I have always been interested in studying the ethnobiological knowledge of traditional knowledge holders in the tropics, including Papua New Guinea, and how this knowledge is declining in the face of rapid cultural and socioeconomic changes, as well as the associated implications for cultural and biological diversity preservation and environmental management.

As the decline is notably rapid among younger generations, my PhD study focused on investigating the socioeconomic drivers of the decline in ethnobiological knowledge and indigenous language skills among young people in Papua New Guinea and Cameroon.
My postdoctoral research examines and compares the traditional use of tagged trees in permanent forest dynamic plots in the lowland forests of Papua New Guinea for medicine, food, materials and other cultural practices. It also looks at how communities manage and preserve tagged tree resources and related traditional knowledge, how knowledge is passed down through the generations, and how environmental change and modernization affect this knowledge.
