"We medical photographers have a behind-the-scenes look at the workings of the human body," says Norman Barker, Ed '85 (MS), associate professor of pathology and art as applied to medicine. Below, Barker's camera hasn't captured rocks polished by roiling seawater, but stones made of crystalline deposits that develop in the gallbladder. "While they may appear to us as burnished charms, their patina belies their actions, as they are known to cause excruciating pain in many people who harbor them," he says.
