I am an associate professor in the philosophy department at the University of Maryland, College Park. My area of specialization is ancient Greek and Roman philosophy. I am currently working on Plato’s ethics and politics in the Republic, Statesman, and Laws. I focus in particular on Plato’s notions of friendship, virtue, beauty, and happiness, and the relationships among these. I am also interested in ancient Greek and Roman moral psychology,  particularly the distinction between rational and non-rational motivation, and the nature of the emotions.
