Simon is an anaesthesiologist and diving physician and is the Head of the Department of Anaesthesiology at the University of Auckland. He has been a lifelong passionate diver and was a lead member of teams that were the first to locate, dive and identify 3 deep shipwrecks of high historical significance in Australia and New Zealand. At the time of one of these dives it was the deepest (180m) ever undertaken to a wreck. He is widely published, particularly in the area of diving medicine, with over 130 scientific papers or book chapters which include the chapter on hyperbaric and diving medicine in Harrison’s Principles of Internal Medicine. His research interests include the pathophysiology of decompression sickness, the respiratory physiology of rebreather diving, and human factors interventions to improve safety in medicine and diving. Simon was elected to Fellowship of the Explorers’ Club of New York in 2006. He received the Albert R Behnke Award (the highest American award for scientific contributions to the field) in 2010, the Eurotek Discovery Award in 2014, and was the Rolex Diver of the Year in 2015.
