Our Team

Michael Nolan
Michael Nolan was born in Bitburg, Germany to an Air Force family stationed there. His first experience of the ocean came at age 12, when he learned to snorkel in the Italian Mediterranean. At age 17 he moved to Tucson, Arizona and became a PADI SCUBA instructor, before starting a SCUBA diving business that specialized in diving trips to the Sea of Cortez. Michael has since begun a new career in marine photography. He worked with National Geographic dolphin researchers in the Bahamas throughout the nineties, as well as running trips to the Silver Banks in the Dominican Republic to study and photograph Atlantic Humpback Whales. Today he is an award-winning photographer who specializes in intimate portraits of marine animals. He has traveled the oceans of the world in search of the world's most magnificent beings. His photography has appeared in hundreds of magazines, calendars, and books in over 45 countries worldwide. He currently "migrates" with the whales, spending his winters in the warmer tropical latitudes where whales mate and give birth and his summers in the cooler higher latitudes where animals migrate to feed.

Jennifer Davidson
Jennifer Davidson has been a lifelong lover of wide open spaces. She grew up in a ranching family in remote West Texas. Her roots run many generations deep in that land, which she has always considered home. She studied marine biology on the shores of the Gulf of Mexico, participating in monitoring projects in the bays of Texas’s Coastal Bend Region and the Flower Gardens National Marine Sanctuary. In 2005, she moved back to the drier climates, this time to the mountains of Northern New Mexico, to pursue a career in photography, which had been a lifelong source of enjoyment. Jennifer has photographed across the globe, focusing her lens on cultures, wildlife, and landscapes to tell the stories of the places she visits. Jennifer has taught photography workshops throughout the United States with National Geographic Expeditions and the Santa Fe Workshops. Her work from South America and the Galapagos Islands has been published in National Geographic Traveller (UK). As a passionate and patient instructor, she enjoys teaching photographers to see the world in new ways through their cameras. Since she began traveling with Lindblad Expeditions in 2007, she has served as a photo instructor in Alaska, the Amazon, Baja California, Cuba, Europe, Galapagos, the Mediterranean, the South Pacific, and Southeast Asia.

Steve Morello
Steve Morello has had a long and colorful career in the natural history world. Born in New Jersey he was lucky to be able to summer on the shores of Cape Cod. Whether it was exploring the tidal pools, snorkeling along the beach, or hiking in the dunes, it all came together to instill in him a deep connection to the natural world. It was no surprise that he would return to the Cape as a whale researcher in his adult years. It was on the Cape that Steve first became involved in guiding, and for 15 years acted as naturalist on whale watching boats in the Gulf of Maine. Steve worked with groups creating environmental education material for school programs and soon found another one of his passions, photography. Well known as a professional wildlife photographer and guide, Steve’s work has appeared in countless publications, including National Geographic magazines and books, The New York Times , and photo collections of the World Wildlife Fund. Steve has written numerous magazine articles on the subjects of travel and nature photography. He is the author of The Traveling Nature Photographer , which has been acclaimed as a must-have for anyone who travels and is interested in photography. Although now a photographer more than anything else, he stays active in the research field and is on the Board of Directors of the Alaskan Whale Foundation, where he assists on research of the whales of Southeast Alaska. Steve is also working on a new project off the coast of Peru where sustainable tourism, scientists, and local fishermen will be working together to conserve a newly created marine sanctuary.

Jeff Campbell
Jeff Campbell fell in love with the ocean while attending boatbuilding school in Eastport, Maine. Since completing his MS in Marine and Estuarine Science at Western Washington University, he has worked for NOAA documenting the ecological impacts of transoceanic fiber-optic cable; the Washington Department of Fish & Wildlife developing an aging method for sixgill sharks; the Lummi Tribe as a Harvest Biologist; Northwest Indian College teaching Fisheries and Wildlife Biology, and as a volunteer for the Whatcom County Marine Mammal Stranding Network. He has been involved in research developing mitigation methods for harmful algae blooms, sterilization methods for oil tanker ballast water, and techniques for screening refinery effluent for harmful ecological effects. He also served as Principle Director on a USDA-funded grant using student interns to study the impact of nutrient-rich run-off on seasonal dead-zones in Bellingham Bay. Jeff is passionate about the marine environment, particularly the northeast Pacific, and believes that the key to preserving this fragile biome is lighting the spark in others by sharing his knowledge on the interconnectedness of seemingly disparate systems. He is particularly interested in the effects of ocean acidification on the larval stages of mollusk, and arthropod larvae. Summers for the last three years have found him driving expedition landing craft and sharing the joys of whale watching with guests. A Lummi Island, Washington resident for more than 18 years, Jeff lives with his wife Penny, who has been a marine naturalist on whale watch boats in the Salish Sea for many years, and their cat, Boo.

Ashley Karitis
Ashley was raised in Central Oregon where she spent her childhood ski racing, riding horses, playing classical piano, and working summer jobs on a dude ranch. She then attended the School of Cinematic Arts at the University of Southern California in Los Angeles earning degrees in cinema-television, history, and international relations. Although immersed in the studies of narrative filmmaking, she gravitated toward the process, deeper on-camera conversations, and scientific and human themes explored in documentary production. Since graduating from USC, Ashley has produced, directed, photographed, and edited feature and short film projects that have ruminated on octogenarian romance, followed grassroots peace activists, and depicted a myriad of characters and cultures. She helped to produce documentary and public broadcast series such as History Detectives, Time Team America, and Oregon Field Guide that have taken her to the aisles of the Library of Congress, pits of archaeology digs across the United States, and to remote communities in the Americas, Africa, Central Asia, and more. As a Video Chronicler, Ashley enjoys the great privilege to be behind the camera shooting wildlife in remote & scenic environments and editing together a compelling, authentic story. Ashley currently resides in Bend, Oregon, and when not on assignment, enjoys skiing, hiking, horses, rock climbing, and water sports.

Amy Malkoski
Amy was raised near Cape Cod in coastal Marion, Massachusetts, and her relationship with the ocean and nature has always been an active one. Her parents, avid divers and marine biologists, introduced her to the underwater world when she was very young and she grew up participating in as many water-related activities as possible. Amy spent her summers sailing and exploring intertidal areas of Buzzards Bay. At age 12 she became a certified diver and is now a divemaster with the National Association of Underwater Instructors (NAUI). In high school her passion for nature and art developed into a love of photography, using the medium to share her explorations with others. Amy studied visual arts with a concentration in photography, as well as studying anthropology and sociology at Roger Williams University in Rhode Island. While studying, she worked as a lab assistant at a shellfish hatchery in Rhode Island where she gained experience in the husbandry, reproduction, and planting of shellfish, with a focus on oysters. Her interests in the undersea, photography, and the study of cultures have allowed her some wonderful experiences, including developing and leading a land tour and diving trip to the Azorean Islands of Portugal. She has dived and worked in Roatán, Honduras, throughout the U.K., and in the cold waters of Arctic Svalbard, Greenland, the Norwegian fjords and Iceland. Since joining Lindblad Expeditions, Amy has pursued her love for cold water diving and exploring unique regions. Her appreciation for the diversity of life, culture, and art means she’s always looking forward to the next adventure. Quite at home on the sea, she hopes to share her passion with others and inspire in them a love for nature and all of its inhabitants.

Andy Wolff
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. Having traveled everywhere from Madagascar to Moscow, Andy’s happy place is amongst icebergs and whales on a sunny Antarctic summer day. When not aboard ship, he often winters near tropical seas, typically hunting below the water’s surface for nudibranchs. A happy Pacific Northwest transplant, Andy now calls the evergreen forests of Olympia, Washington home. There he enjoys crafting homemade soap, trail running, and consuming copious quantities of coffee. If you end up sharing a table in the dining room one evening, be sure to ask about his international gold medal in barbershop. Andy was thrilled to join the Lindblad Expeditions team in 2010. Among so much photographic talent, he is a firm believer that the best camera is the one you always have with you. For a look at life through his lens, investigate instagram.com/travelingandy.

Jen Hayes
Underwater photographers David Doubilet and Jennifer Hayes are married partners who work together as a team to produce National Geographic stories from equatorial coral reefs to beneath the polar ice. David estimates he has spent nearly half his life in the sea since taking his first underwater photograph at the age of 12 with a Brownie Hawkeye camera sealed in a bag. Between them, Jennifer and David have photographed and explored the ocean depths in such places as New Zealand, Canada, Japan, Tasmania, Scotland, and Antarctica. David has photographed stingrays, sponges, and sleeping sharks in the Caribbean, as well as shipwrecks in the South Pacific, the Atlantic, and at Pearl Harbor.

Nick Brown
Born and raised on the edge of the Mojave Desert, Nick was accustomed to hot dry days, far from the ocean. Everything changed when he attended California State University Monterey Bay, a short 1.5 miles from the beaches of Central California. This is where Nick’s passion for the water developed and completely engulfed his life. He quickly changed his concentration in college to Marine Science, allowing him to further dive into the underwater world. Nick’s affinity for the water tripled when he discovered SCUBA diving. He even applied diving into his research of the kelp forests of Monterey Bay. During his schooling, Nick became an AAUS Scientific Diver and SCUBA Instructor, allowing him the credentials to become a Dive Safety Officer (DSO) for The Monterey Bay Aquarium. Immediately after graduating with a degree in Marine Science, Nick was offered a full-time job as a DSO at The Florida Aquarium. In Florida, Nick’s need for exploration grew as he discovered new experiences for himself – everything from deep underground caves to beautiful coral reefs. Nick’s passion then led him to pursue a career in Marine Education and Safety. He currently works as a DSO at The Oregon Coast Aquarium and a lead naturalist for Marine Discovery Tours in Newport, Oregon. Nick’s enthusiasm for the natural world is contagious and he looks to create meaningful ways to connect people to the underwater world, through diving and snorkeling. His greatest goal in life is to inspire stewardship of the Oceans in hopes that one day everyone will want to protect this beautiful blue world as he does.
