Cami is a biologist who has always been fascinated by animals. During her childhood, she spent countless hours observing all kinds of critters in the wild and reading books to understand them better. She was blown away by their intelligence, their ability to adapt and their distinct personality. This curiosity coupled with her willingness to protect our nature led her to pursue a bachelor in Biology at the University of Neuchâtel in her home country of Switzerland. The ocean already had a special place in her heart, but she fell in love with fishes during a zoology class, when Cami realized how many misconceptions we have about them and how little we know. She completed her MSc degree in Animal Behaviour and Chemical Ecology. Her MSc thesis focused on the cleaning mutualism among the cleaner wrasse (Labroides dimidiatus) and their client reef fishes on the coral reefs surrounding Lizard Island Research Station in Australia. Cami collected behavioural observations as well as blood samples to investigate whether an experimental reduction in cleaners density affects the service quality provided by cleaners to their clients. She also explored whether client fish suffer from having reduced access to cleaning services by measuring their physiological responses . After graduation, Cami interned at the CORE sea research centre in Thailand, the Bimini Biological Field Station, and the Whale Shark and Oceanic Research Center in Utila, Honduras. She then worked a year in the Maldives as a Marine Biologist and 2 years in the Cayman Islands as a SCUBA Instructor. Cami is now working as a Mission Director at Jule’s Undersea Lodge in Key Largo, where she teaches aquanauts about underwater research stations and conducts underwater laboratories. She is thrilled to be a part of OFI, to make a difference by educating the younger generations and by monitoring the population of key marine species in the hope to protect them with well thought out conservation plans.
Ethan has always had a passion for the outdoors, particularly in the oceans. Living landlocked for most of his early life, he was delighted when his family moved to Cape Cod, Massachusetts. After completing high school in rural Pennsylvania, Ethan completed a Bachelor of Science double majoring in Biology and Environmental Science at the College of William & Mary in Williamsburg, VA, concentrating on marine ecology and conservation. While completing his undergraduate degree, Ethan took part in several research projects in ecology, including a crayfish population survey in the Lake Matoaka watershed via baited trap and netting methods, a camera trap wildlife survey via photo/video analysis, and invasive blue catfish osmoregulatory and electroreceptory capacity in the Chesapeake Bay. Ethan served as a research intern at the Bimini Biological Field Station, or “Sharklab”, in South Bimini, the Bahamas, where he spent his days diving and photographing many shark species, including the endangered Great Hammerhead. Ethan is currently a marine science instructor at MarineLab Environmental Education Center in Key Largo, FL, where he can be found on a boat somewhere in either the Florida Keys National Marine Sanctuary or Everglades National Park with school groups aged fifth grade through college and adult-level teaching them about seagrass, mangroves or coral reef ecology. Ethan is excited to be a part of OFI, combining research with education, and is looking forward to completing projects tracking shark population health and abundance in and around the Florida Keys.
