Jeffrey Bozanic is an extremely active technical diver and instructor. Specializing in rebreather use, he is probably best known for his seminal textbook on the topic, Mastering Rebreathers (Best Publishing Co.).
Jeff holds an MBA in International Marketing, a Ph.D. in Education, and spent another three years in Ph.D. level studies in marine geochemistry.
Jeff has worked for over 20 years as a management consultant, both within and outside the dive industry. He has also performed services as an accident investigator and expert witness, consulting on cases related to scuba fatalities and non-fatal dive related incidents.
Jeff’s scientific diving began in 1978, when he was working on his thesis for his degree in geology. He spent a year dredging for gold, analyzing the settling velocity of natural alluvial gold particles. He later studied the effects of water chemistry in underwater cave systems, and has collected many new animal species from submerged caves. In addition to his research, he has overseen scientific diving programs in Antarctica as part of the U.S. Antarctic Program, the University of Southern California as Diving Safety Officer, and on multiple diving control boards of various academic diving programs.
Jeff started teaching technical diving in 1983, long before the term “technical diving” was coined. Originally specializing in cave and decompression diving instruction, he later branched out into teaching nitrox and trimix. He currently conducts rebreather, cave, nitrox, advanced nitrox, decompression procedures, and trimix diving courses, as well as instructor courses.
He has published extensively on diving education topics, with heavy emphasis on cave and rebreather diving. He has edited/reviewed many diving textbooks, including co-authoring the Antarctic Scientific Diving Manual and editing The NOAA Diving Manual.
Jeff served on the Board of Directors of NAUI, NSS Cave Diving Section Board, IANTD Board of Advisors, and the TDI Rebreather Advisory Board.
His contributions to diving safety have been recognized with many awards, including the Platinum Pro 5000, Silver Wakulla, International Safe Cave Diving, NAUI Hall of Honor, TDI Professional of the Year, the 2007 DAN / Rolex Diver of the Year, and in 2014 received NAUI's Lifetime Achievement Award. His contributions to underwater sciences were recognized by the American Academy of Underwater Sciences' Conrad Limbaugh Award for Scientific Diving Leadership in 2015.
