I am a Serra Húnter Fellow at the University of Barcelona who works on ancient Greek philosophy, primarily Plato and Aristotle. I have been a visitor at Clare Hall, Cambridge, supported by a Spencer Foundation Grant, and a Solmsen Fellow at the University of Wisconsin-Madison. I have previously held positions at Humboldt-University of Berlin, Northwestern University, and UC Berkeley.

My comprehensive book on Plato's Phaedo has recently been published with Cambridge University Press. It works through the dialogue in order, providing new interpretations of a number of the dialogue's famous ideas, including the nature and existence of "Platonic" forms, the immortality of the soul, the method of hypothesis, the theory of causation, and the contemplative ethical ideal. It also carefully considers less discussed parts of the dialogue, including its cosmology, literary structure, portrayal of character, and engagement with ancient medicine and religion.
