Meet Our National Geographic Experts

National Geographic’s researchers, explorers, and storytellers have been inspiring people for more than 125 years. They’ve pursued their dreams, become leaders in their fields, and are excited to share their stories and knowledge with students. National Geographic experts join all of our programs except for our community service trips. As you explore together, they’ll share their insights and experiences, give you guidance in crafting your final project, and inspire you with their passion for the work they do and the places you’ll discover together. Meet the experts who will join our trips this summer.

David Gruber

National Geographic Emerging Explorer and grantee David Gruber is a marine biologist and ocean explorer who searches the undersea world for bioluminescent and biofluorescent marine animals. By studying these creatures, he has uncovered a secret "language" of shining colors and patterns that help many marine creatures communicate, interact, and avoid enemies. On land, his team designs submersibles and extremely light-sensitive cameras to aid their deep sea exploration, and works with medical researchers who might be able to use these sea creatures’ molecules as tools to visualize the inner workings of human cells. Committed to the public understanding of science, David’s research and media were featured in an exhibit at the American Museum of Natural History, and his writings have appeared in The New Yorker, Nature Medicine, and The Best American Science Writing. David first developed his interest in glowing marine creatures during an undergraduate reef study in Belize, where he used glow sticks to track the movements of reef fish at night. David will join the July 5 and July 12 departures of the Belize conservation in action program on Blackbird Caye.

Denise Rambaldi

Keith is by far the coolest and most interesting person I've ever met in my life (and probably for the rest of it). He had a profound effect on how I look at both photography and my life. I found his story and work really inspiring and I now cannot wait to further explore the art of photography.

Jennifer W.
Switzerland & France expedition 2014






Ulla is an extremely accomplished photographer, and the greatest explorer I’ve ever met. She made the already great experience of the Daintree Rainforest and the whole Australia trip into an unforgettable one. Her life story was inspiring and she helped me discover my own strengths. She was cheery, smart, caring and just a quality person - it wouldn’t have been the same without her.

Andrew H.
Australia expedition, 2014






It was such an honor to meet Ford Cochran- he was down-to-Earth and positive- I don't think I'd recognize him without a smile on this face! It was an amazing experience to hear about his passions, and I loved how willing he was to help us with our projects and answer any questions we had.

Hattie H.
Iceland expedition, 2014






Tino taught me so much about photography, from how to approach difficult situations to walking slowly and observing places carefully. When I got home, I put his tips to use and my photography has improved so much! I'm excited to see how much further I can go with the lessons Tino shared with us
