Some students sell blood plasma to make extra cash during graduate school. Thomas Lozito, a new professor of orthopaedic surgery and stem cell biology and regenerative medicine at USC, sold poison dart frogs to ward off the impecunity of the PhD years.
“When I was in high school and all the way up to graduate school, my goal was to keep every different species of dart frog,” he said. “They’re beautiful. I would set up a colony, take care of them, and actually breed them. I was able to supplement my income in graduate school with breeding these rare frogs.”
