Mark Busse is Senior Lecturer in Social Anthropology at the University of Auckland. His research concerns social organization, reciprocity and markets, intellectual and cultural property, and inequality with a geographical focus on Papua New Guinea. He has carried out long-term ethnographic research among Boazi-speaking peoples in the Lake Murray-Middle Fly area of Papua New Guinea since 1982. That research has focused on dual organization, sister exchange marriage, gender and inequality, history, and regional integration. Before moving to New Zealand in 1999, Mark worked for nine years at the Papua New Guinea National Museum first as Curator of Anthropology and then as Assistant Director for Science, Research and Consultancy. His current research, which is funded by the Royal Society of New Zealand, concerns the fresh food market in Goroka in the Eastern Highlands Province of Papua New Guinea. It addresses issues of urban food security through an examination of the market as a set of complex social relations and from the perspectives of the diverse participants in the market rather than through the application of Western economic models. He is co-editor of Protection of Intellectual, Biological and Cultural Property in Papua New Guinea with Kathy Whimp (published by ANU Press) and Ownership and Appropriation with Veronica Strang (published by Berg).
