Everyday Exporations

Dr. Elizabeth Kapu'uwailani Lindsey is an award-winning filmmaker and anthropologist. She is committed to ethnographic rescue, the conservation of vanishing indigenous knowledge and tradition. Dr. Lindsey earned her doctorate studying and documenting the nearly lost traditions of the palu, Micronesian non-instrument navigators. Lindsey's expeditions now take her to some of the most remote regions of the world.
