Biography

Dr. Renie Guilliod is an anesthesiologist and a hyperbaric and diving medicine specialist, with expertise in the treatment of non-healing wounds and lymphatic disorders (lymphedema). He joined the UT Southwestern faculty in 2016, and leads the team that maintains the state-of-the-art care and academic program of the Hyperbaric Medicine Unit - Institute for Exercise and Environmental Medicine, located at Texas Health Presbyterian Hospital Dallas, which is long standing collaborative program between UT Southwestern and Texas Health Resources (see www.ieemphd.org ).

He earned his medical degree and completed his residency training in anesthesiology at the Central University of Venezuela. He is one of the first physicians to be fellowship-trained in hyperbaric and diving medicine following graduation from the University of Maryland Medical Center in Baltimore. He also trained in diving and hyperbaric medicine with the United States Navy and the National Oceanic and Atmospheric Administration (NOAA). In 1994, he received recognition as a U.S. Navy Diving Medical Officer (first civilian foreigner to complete this training, graduating with honors). He is a bell/mixed-gas/saturation diver and supervisor, as well as a Diving Medical Advisory Committee and European Diving Technical Committee (DMAC/EDTC) med level IIb, certified to perform fitness to dive examinations and manage diving accidents.

Dr. Guilliod was chosen in 1999 as one of the medical directors of Divers Alert Network (DAN) and between 2006 and 2008, he served as President of the Latin-American Chapter of the Undersea and Hyperbaric Medical Society. Between 2005 and 2015, he was Assistant Professor of Anesthesiology and Internal Medicine, and Director of Research of the Division of Hyperbaric Medicine at UT Medical School, Houston. He was in charge of the academic program and led the management of hyperbaric emergencies. His expertise with the care of critically ill patients in hyperbaric chambers was vital to provide this service, which still is only available in a small number of hospital-based hyperbaric oxygen therapy centers.

During the last ten years, Dr. Guilliod’s research work has focused on the study of the lymphatic system in post-cancer treatment patients, patients born with lymphedema, and patients with non-healing wounds. He is part of the team that developed the Near-infrared Fluorescence Lymphatic Imaging System (NIRFLI) that allows the visualization of the lymphatic vasculature functioning in real time. His work has allowed the evaluation of anatomical and functional lymphatic abnormalities and their potential treatments, as well as leading to the discovery of several gene mutations and deletions responsible for triggering lymphedema. This will ultimately translate to discoveries toward treatments and better management of lymphedema and non-healing wounds.

Dr. Guilliod has also been an investigator for NASA evaluating how mild hypobaric-hypoxia affects human brain function, paralleling the type of environment the astronauts will experience in the next generation of space vehicles.
