National Geographic Experts

There are some careers out there that we all dream of having someday. An archaeologist or a filmmaker, perhaps, or a National Geographic photographer. On each expedition and field workshop, you'll be joined by a National Geographic expert -- photographers, writers, anthropologists, wildlife biologists, and explorers who have pursued their dreams and become leaders in their fields. Our experts will join each group for four to eight days to share their insights and experience, give you guidance in crafting your On Assignment project, and inspire you with their passion for the work they do and the places you'll explore. Meet a few of the experts who will join our expeditions.
