Renie Guilliod, M.D.

Assistant Professor of Internal Medicine (Cardiology/Hyperbaric Medicine)
The University of Texas Medical School at Houston

Research Coordinator
Memorial Hermann Center for Hyperbaric Medicine

Dr. Guilliod is an anesthesiologist and hyperbaric and diving medicine specialist. He was recruited in 2004 to The University of Texas Health Science Center at Houston as a Visiting Assistant Professor of Anesthesiology to work in the Center for Hyperbaric Medicine, Wound Healing and Lymphedema Management.

He earned his medical degree and completed his residency training in anesthesiology at the Universidad Central de Venezuela in Caracas. Dr. Guilliod fulfilled a two-year fellowship in hyperbaric medicine and wound healing at the University of Maryland in Baltimore. He also trained in hyperbaric and diving medicine with the United States Navy, the National Oceanic and Atmospheric Administration (NOAA) and the College of Oceaneering. In 1994 he received recognition as a US Navy Diving Medical Officer and US Navy Diver. Dr. Guilliod was the first civilian foreigner to complete this training and graduated with honors.

He is past president of the Latin-American Chapter of the Undersea and Hyperbaric Medical Society. Currently, he is the Medical Director of the Divers Alert Network (DAN) Emergency Network for the northern sector of South America, an international non-profit medical and research organization.

Dr. Guilliod has extensive experience in environmental medicine and exercise physiology, including evaluation and training of high-performance athletes, and supporting some of them to break national and world records. His experience in diving medicine included planning and direction of more than 1,500 dives deeper than 280 feet of sea water, using a variety of breathing gases. One of his current projects is a study to further the understanding of physical underpinnings of cognitive function in hypobaric-hypoxic environments such as those that astronauts will experience in the next generation of space vehicles.

His research areas of interest include: hypobaric/hyperbaric and hypoxic/hyperoxic environments, oxidative stress, ischemic reperfusion injury, endothelium and lymphatic system.
