James is a Fellow at the Center for Hellenic Studies at Harvard University. Previously, he was an Assistant Professor of Classics at the University of Southern California. His research includes ancient philosophy, Greek literature and cultural history, and his dissertation was titled "Philosophical Advertisements: Protreptic Marketing in Fourth-century Greek Culture" (advised by Andrea Nightingale, Richard P. Martin, and Josiah Ober). He has helped to develop a new course titled “Performing Wisdom,” which examines how philosophical theory and practice, thoughts and deeds together contribute to the philosophical art of constructing, performing, and becoming the right sort of character. Additionally, in 2010, James taught courses on ancient science and the pragmatics of cultural production.
