  • Andy Wolff

    Assistant Expedition Leader
    A Midwestern kid with an insatiable curiosity about places far and foreign, Andy has converted a lucky break after college into a career at sea. From swabbing the decks to advocating for artisans and zooming in Zodiacs, he knows the operation from every department on board. What keeps him fresh after nearly two decades working at sea is waking up somewhere new every morning, the day ahead a blank slate with no way of knowing what marvels nature and serendipity may bring his way. Andy looks forward to sharing this sense of wonder and possibility with guests as they venture together into new realms with Lindblad Expeditions-National Geographic.

  • David Helfand

    Guest Speaker
    David J. Helfand, a faculty member at Columbia University for thirty-nine years, served half of that time as Chair of the Department of Astronomy. He is the author of nearly 200 scientific publications and has mentored 22 PhD students, but most of his pedagogical efforts have been aimed at teaching science to non-science majors. He instituted the first change in Columbia's Core Curriculum in 60 years by introducing science to all first-year students. In 2005, he became involved in the effort to create Canada's first independent, non-profit, secular university, Quest University Canada. He was a Visiting Tutor in the University's inaugural semester in the Fall of 2007 and served as President & Vice-Chancellor from 2008 to 2015.

  • Dennis Cornejo

    Naturalist
    Dennis began scuba diving during the mid-1970s as part of a research project. At the time he was a research associate at the Arizona-Sonora Desert Museum in Tucson, Arizona, studying the population of winter hibernating sea turtles.  What began as a scientific study soon became a conservation project that expanded to three species of sea turtles along the entire Pacific coast of Mexico.  This project received major funding from the World Wildlife Fund and was eventually taken over directly by that agency with Kim Clifton and Dennis Cornejo as co-principal investigators.

  • Doug Gualtieri

    Naturalist
    Doug’s passion for the natural world started at an early age in his home state of Michigan. He received two biology degrees from Central Michigan University, and later went on to get a master’s degree in conservation biology. His education led him to study a diverse range of natural sciences, with an emphasis on ecology, animal behavior, and migratory birds. Shortly after leaving the academic world, Doug migrated north to Alaska with his trusty Siberian husky, Koda. He began working as a naturalist in Denali National Park in 1999. For over seven years he has shared his love of Alaska and Denali’s six million acres with Lindblad Expeditions-National Geographic guests, as trip leader for the Denali Land Extension based at the North Face Lodge deep within the park.

    Naturalist
    Edward Shaw has travelled widely as a naturalist and guide. For the past 18 years, Edward has lived in northwestern Patagonia initially working as a teacher and subsequently working in community projects. This remarkable region of South America is home to many incredible geologic features — fiords, glaciers, volcanos, and lake basins long ago excavated by ice-streams — unique flora and fauna, as well as the archaeological remains of pre-Columbian civilizations dating back to at least the 13th millennium BCE. He is deeply committed to the principles behind sustainable development and currently works for a local foundation.

  • Ella Potts

    Naturalist
    Growing up, Ella spent much of her time swimming and kayaking in the cold waters off the rugged coast of West Wales. It was there that she first found her love of the ocean. From those early beginnings she went on to study Biology at undergraduate degree and Environmental Biology, Conservation and Resource Management to Masters degree level, at Swansea University. During her studies, Ella took an ecosystem approach towards assessing the health of our marine systems, with her specialism being in our oceans apex predators, the cetaceans. Following her studies, Ella decided to put her scientific background to good use and move into marine conservation.

    With a bachelor’s degree from Wales and a Ph.D. from Scotland, Gail has used her skills in marine biology to pursue her passion: investigating marine biodiversity all over the world. As a research scientist based in San Francisco, she has led projects in coastal marine communities from Alaska to Panama. A cold-water diver at heart, Gail jumped at the opportunity to lead a research project on the impacts of climate change that involved spending two years diving under the ice in Antarctica. Other projects have taken her to Florida, Guam and Indonesia.

  • James Hyde

    Undersea Specialist
    James is your typical free-range Pacific Northwest outdoorsy type. Born in Seattle and reared nearby on Vashon Island, he is most comfortable in slightly cold and damp weather. James joined the Lindblad team in July 2016 as a dive buddy and has been in love with expedition travel since. On his own he has traveled to Europe, Asia, and Australia, but with Lindblad he hopes to continue his adventures across the globe, searching out the beauties of the natural world. An avid scuba diver James can’t help being excited about whales, sharks, and pinnipeds, but he will also happily bend your ear about underwater slugs and invertebrates. It’s best just to humor him about these things.
