Naturalist
Daniel Baldwin
An educator at heart, Dan finds great joy in helping others explore and connect with the world around them. He has taught marine sciences in the Florida Keys and on Catalina Island, science and math in international schools in Mexico, Costa Rica, and the South Pacific, and swimming and water safety in Alaska. Dan grew up in Pennsylvania and attended Penn State where he earned a degree in science education. He has always sought out fulfilling work, in beautiful locations, surrounded by wonderful people. Connection with the environment has been a constant theme in his work and travels. At present, Dan has returned to his roots in Central Pennsylvania where he and his wife have settled and spend their time in the great outdoors. While on board with Lindblad-National Geographic he can be found engaging folks in the natural world; and is always on the lookout to provide enlightenment for naysayers of the green flash.
Naturalist
Timothy Martin
Tim Martin has been teaching Geology, Astronomy, Art and Earth Science for over 20 years. Although he grew up in several locations around the United States, he always felt most at home in the natural world. His persistent curiosity led to his undergraduate study of the natural sciences and art, and his love of teaching led to graduate work in Geoscience Education. Beyond classroom study, he has worked with an international Climate and Geologic research expedition in Siberia, he and colleagues flew an experiment on NASA’s zero-gravity research plane, studied volcanoes in Hawaii, and in 2016 Tim was selected as a National Geographic and Lindblad Expeditions Grosvenor Teacher fellow. Tim has taught Art in addition to the science classes. Helping students explore their creative side through photography along with learning the technical aspects of working with and firing clay has been a wonderful extension to his scientific and aesthetic pursuits. In his free time, Tim is an active artist, and he enjoys all sorts of outdoor activities with his family. Frequently on weekends you may find him “up close and personal” with Earth Science while hiking and rock climbing.
Cammy Lachesnez-Heude
Cammy was born in Martinique but didn’t quite stick around long enough to learn French, but she’s working on it! Her family relocated to the Sunshine State of Florida where the Gulf of Mexico was a five-minute bike ride away (not including the very necessary ice cream stop along the way). The majority of her childhood was spent eating oranges while perched in the trees of her backyard or cutting her feet up while calf deep in mangrove estuary muck. While she loved the weird and wacky creatures of Florida, California was calling. Off to University of California, Santa Cruz she went to become a banana slug under the redwoods while majoring in Environmental Studies and Politics. Environmental Law seemed the next logical step but a bison ranch, Australian cruise ship, and currently Lindblad all seemed like reasonable speed bumps along the way. Cammy’s dream creature to see in their natural habitat is a Narwhal, so if you have seen one, tell her all about it! You can find her behind her desk, partaking in a polar plunge, hiking ridges, or madly searching for creatures from the bridge.
Undersea Specialist
Christine West
Christine is an Explorer's Club Fellow, Polar Expedition Diver, Expedition Leader and conservation photographer and videographer. She has worked as a professional diver around the world for over 18 years dedicated to ocean education, exploration and safety. Christine proudly became a USCG certified 100-ton Captain in 2017. She now spends over six months per year in the field documenting and sharing stories about places that are rarely seen and yet are rapidly changing due to the warming of the Earth such as the High Canadian Arctic and Antarctica. Christine uses a variety of tools such as underwater cameras, drones and ROVs to create imagery that serve as voices for ecosystems that need immediate protection. It is important to her to not only document species presence and abundance, but to share their stories and behaviors in a memorable way that drives wider audiences, including inland communities, to care about places that may not be in their backyard but to which they influence and are connected. Christine's passion to share the lesser-known stories continually pushes her to dive the coldest, sometimes murkiest, most remote areas on the planet. Christine was fortunate to grow up in the Pacific Northwest along the shores of the Puget Sound. However, she has called the Big Island of Hawaii home since 2014 and plans to continue building her future with her husband there.

Naturalist
Santiago Imberti
An ornithologist, photographer, fisherman, climber, and writer, Santiago Imberti was born and raised in southern Patagonia, Argentina. He obtained a degree in tourism and later in ornithology, which allowed him to combine his love for nature and the outdoors with his work as a birdwatcher, naturalist, fly fishing, and mountain guide. He has been guiding trips in Patagonia, the Antarctic, and Arctic for some 25 years. However, his main passion is conservation and research therefore off the ships Santiago does field work on birds, mostly in southern Patagonia and is the President of Asociación Ambiente Sur; an NGO that seeks to protect the environment and educate the new generations on a sustainable way of life in southern Patagonia. From 2009 to 2014 he has coordinated the project to save the now critically endangered Hooded Grebe, which is an endemic bird in Patagonia; and the creation of Patagonia National Park, a massive protected area that aims to save the grebe and some of the least know habitats in South America. His many articles and stories have been published in scientific journals, popular travel magazines, books, and since his singing abilities are rather poor, he has produced a couple CDs of the beautiful bird sounds of South America, Patagonia, and Antarctica. He lives in Punta Arenas, southern Patagonia, Chile, with his wife and son.
Naturalist
Eva Westerholm
Eva is an animal loving outdoor enthusiast who has guided in the polar regions and many of the countries in between for over 15 years. She grew up on the west coast of Sweden and travelled extensively with her family throughout Europe. Eva credits this early exposure to new cultures as an inspiration to keep exploring and has not slowed down since. Looking for an adventure of her own, she took a job as mess girl on a small vessel in the Arctic Archipelago of Svalbard under the midnight sun. Eva fell in love with the sea and has not stopped sailing since and now has worked nearly every role possible on expedition ships. Not only is Eva an avid birder and a keen naturalist, but she is also very interested in human history and the stories people and places tell. Wanting to learn more she studied at the University of Gothenburg and University of Sydney Australia where she has earned a degree in Social Anthropology. Eva loves sharing her knowledge and experiences, but she values what she learns from her fellow travelers, guests, and colleagues, even more. Currently Eva lives in the beautiful San Juan mountains of Colorado where she enjoys skiing, hiking, and biking. Her work and travelling lifestyle do not allow for a pet at home, so the closest thing to it is a sourdough starter that she has managed to keep alive for over 8 years.
Cultural Specialist
David Brotherson
Growing up near Sydney, Australia, as a student David was long captivated by science, astronomy, and aviation. His passion for the world’s cultural diversity - and it’s elaborate, often entangled history - developed later, and was rooted in a fascination with the civilisations, history, and mythology of the ancient Mediterranean. These interests took shape at the University of Sydney as an archaeology major. As his undergraduate studies neared completion, David started travelling the world, and he would make a transformative trip to Southeast Asia. His weeks abroad were a fairly balanced mix of sandy beaches and medieval ruins but would culminate in a life changing experience standing amidst the enigmatic temple complex of Angkor Wat in Cambodia. The opportunity then arose to work with the university’s Greater Angkor Project, a multi-disciplinary archaeological research program, and a PhD scholarship further cemented this collaboration. David’s dissertation on Angkor’s decline - founded in his expertise in settlement archaeology and GIS - integrated analysis of ceramics, the engineered landscape, environmental proxies, and international trade networks to analyse its urban trajectory, demise, and transformation. David is a long-term resident of Siem Reap, Cambodia, where he has lectured and led tour groups for over a decade. His role with Lindblad-National Geographic began in 2015 with the Mekong River voyage and has since broadened to various Mediterranean programs as expedition historian. David received his PhD from the University of Sydney in 2020. His archaeological research in Cambodia is ongoing, as is his passion for world history, educational tourism, playing guitar and tennis.
Emily Hyde
Emily grew up in the beautiful, rainy Pacific Northwest. Born and raised on Vashon Island, she then moved to nearby Seattle to attend the University of Washington. After completing her degree in English Literature, Emily spent the next year preparing for and hiking the Pacific Crest Trail with her older brother. There she discovered a passion for backpacking and spent the next few years walking all over the world, from the Te Araroa trail in New Zealand to the Spanish El Camino to the Laugavegur trail in Iceland. The up close and personal nature of long distance hiking led Emily to her passion for sustainability and the natural world. Certified as a Master Composter and Sustainability Steward from Seattle Tilth Alliance, she is regularly found elbows deep in worm bins or engaged in in-depth discussions about Leave No Trace principles. Her combined passions for travel and conservation have led her to yet again follow in her older brother's footsteps (although not so literally this time), as a member of the Lindblad Expeditions team. Off the ship, Emily likes to be practicing her homesteading skills by baking bread, making jam, and experimenting with fermentation. When not in the kitchen she can be found in the mountains hiking, climbing, or practicing sun salutations.
Expedition Leader
Dave Katz
Dave grew up in a village in the heart of the rural Finger Lakes region of New York and at an early age fell in love with the outdoors. Dave’s mother, a high school earth science and biology teacher turned weekend hikes into informative lessons. The beautiful gorges, various lakes and hard wood forests made a lasting impression on him. At university, he continued to pursue his growing interest in the natural world through study of Geology and Ecology. At this time, he joined the Outdoors Club and began leading caving, rock climbing and winter camping trips with fellow students. After obtaining a bachelors degree in Geology at Binghamton University, he set out to explore the world, working seasonally as a wilderness field instructor while in the offseason pursuing a growing interest in photography and storytelling. Inspired by the desire to explore and learn, his prolific travels have drawn him to over 85 countries on all seven continents. His storytelling work has been published on television, in print and on the internet with HBO, Nat Geo Kids, PBS Nature and Outside Magazine. Identifying strongly with the concept of “Tenacity in Pursuit,” he aims to inspire curiosity through his work as a field educator and professional storyteller. Since 2004, he has led over 20 exploratory tree climbing expeditions to forest canopies around the world through his work with Cornell University’s Tree Climbing Institute. Always excited and ready for the next location, challenge or project, he is a proud member of the Lindblad-National Geographic Expedition Staff team.
Historian
Douglas Kenck-Crispin
Doug Crispin is a historian who honed his craft at Portland State University (Hist. BA, MA) in Portland, Oregon. A lifelong resident of the Pacific Northwest, he has been captivated by the exploits of exploration since he was a boy, and he has continued his professional career with that same infatuation. He is a filmmaker, journalist, and historical consultant who loves sharing the stories he discovers. Doug relishes researching documents at regional archives and burrowing through the back of musty used bookstores, but nothing compares to voyaging the same historic terrain, and seeing the sights as our predecessors saw them, from the perspective of the water line and beyond. Whether in Lewiston, Idaho, or Santiago, Chile, Doug likes to explore local breweries, wineries, and restaurants noted for their regional cuisines, so be sure to ask him for a recommendation! A seasoned traveler, Doug has extensively explored Southeast Asia, South America, and most recently, Belgium. When not investigating historic sites up and down the Columbia and Snake, Inland Passage, Antarctic, and all points beyond, you'll find him at his cabin on Puget Sound, shucking oysters, reading history books, and trying to figure out where D.B. Cooper stashed all that dough.
