In high school, Joshua D. Sosin had two favorite subjects: Latin and biology. "In the end I decided that my Latin teacher was cooler, and if I, too, wanted to be cool, I should do Latin," he says. That led to a concentration in classics, philosophy, and religion at what is now the University of Mary Washington, where he studied not only Latin but also Greek and Egyptian Coptic. He got a Ph.D. in classics from Duke University in 2000. "At no point did I consider what I would do with any of this," he says.
