Congratulations to physics division director Dr. Sha Chang for being featured in UNC Endeavors magazine, the official research and creative activity magazine of UNC-Chapel Hill. Her work, in collaboration with Dr. Otto Zhou, David Godschalk Distinguished Professor of Physics and Astronomy, involves the use of a nanotechnology-based microbeam irradiator to deliver very high doses to tumors – much higher than is currently possible – while avoiding damage to surrounding normal tissues.
