David Ebrey's (Ph.D., UCLA) main research interests are in ancient philosophy. His dissertation, Aristotle's Motivation for Matter, focuses on issues in ancient metaphysics and the foundations of natural science. He is in the process of writing a book on the role of matter in Aristotle's natural science, which will draw from his dissertation, but mostly be new material. He also has strong interests in ancient epistemology and ethics, having recently written a series of articles on Socrates’ search for knowledge. In recent years he has taught a survey course on ancient philosophy, a freshman seminar on Socratic dialogues, and graduate seminars on Plato’s Meno, Plato's Phaedo, Aristotle’s Physics II, and Aristotle's Metaphysics Beta.
