UC Irvine postdoctoral researcher Dr. Bertrand Tseng (pictured) is one of four young investigators to be named a National Space Biomedical Research Institute fellow. The two-year program offers fellows the opportunity to manage their own space-related biomedical research project. Tseng, who works in the lab of radiation oncology professor Dr. Charles Limoli, will study how solar radiation increases oxidative stress in the body, which can affect the function and regenerative abilities of muscles and organs. He also will receive a $40,000 stipend and attend a summer institute that provides an introduction to NASA’s research facilities programs at the Johnson Space Center in Houston.
