Oxygen is critical to life. When levels of oxygen change, it can have immediate and lasting impacts on a person's health. Tatum Simonson, Ph.D., associate professor of medicine and John B. West Endowed Chair in respiratory physiology in the Division of Pulmonary, Critical Care, Sleep Medicine & Physiology at the University of California San Diego School of Medicine, has studied the effects of altitude on people across the globe. Her research hopes to uncover the genetic and epigenetic factors that protect against—or contribute to—low-oxygen health issues. Over time, this work could lead to better ways to treat or prevent a wide range of breathing problems.
