Expertise: Altitude Studies

Dr. Beall is a physical anthropologist whose research focuses on human adaptation to high-altitude hypoxia, particularly the different patterns of adaptation exhibited by Andean, Tibetan and East African highlanders. Her current research deals with the genetics of adaptive traits and evidence for natural selection, with the role of nitric oxide in oxygen delivery at high altitude and with the human ecology of high-altitude Tibetan nomads.

Professor Beall is a member of the U.S. National Academy of Sciences, American Philosophical Society, and the American Academy of Arts and Sciences.

Your environment can cause chemical modifications to your DNA that turn genes on or off, or lower or raise the activity of certain genes. The strategy allows people to adapt to their surroundings much more rapidly than pure genetics allows. Still, it’s unclear what role epigenetics plays in helping people adapt to a life at high altitude.
