Dr. David Close is Director of the Aboriginal Fisheries Research Unit at the UBC Fisheries Centre.  Dr. Close is also faculty in the Department of Zoology.  He is a citizen of the Cayuse Nation located on the Confederated Tribes of the Umatilla Indian Reservation. Dr. Close’s research is focused on answering biological questions directed towards sustainable aboriginal fisheries.  His current research focuses primarily on the ancient vertebrate, the lamprey which is a culturally important food to the aboriginal peoples along the west coast.  He conducts interdisciplinary research in the areas of aquatic ecology, fish physiology, chemical ecology, and integrating traditional knowledge and fisheries science.
