I'm a Mellon Postdoctoral Fellow and lecturer in the Philosophy Department at Stanford University. I specialize in ancient Greek philosophy, with particular interests in ancient Greek metaphysics and Plato.

Currently I am most interested in how ancient thinkers from the Presocratics to Aristotle sought to explain (what we'd now think of as) the structure and composition of ordinary objects. I am especially interested in clarifying how Plato fits into this tradition, and showing how his conception of Forms was developed against this background. In particular, I believe that this perspective can help explain the way in which Forms are causes (as they are said to be in the Phaedo), which in turn helps us see that this sort of causality is fundamental to what Forms are.

I began this research in my doctoral thesis, completed in the spring of 2015 at the University of Toronto, as part of Toronto's Collaborative Program in Ancient and Medieval Philosophy, and under the supervision of Rachel Barney. I am now developing this work into a monograph, titled The causal origins of Plato's Forms: The natural philosophy of the Phaedo and its context.

In addition to my work on Plato's metaphysics, I am also interested in (and have papers in progress on) issues in Plato's philosophical methodology, ethics, and philosophy of perception; the concept of beauty (to kalon) in ancient Greek philosophy; and aesthetics and the philosophy of literature.

In my spare time, I enjoy hiking, gardening, rock climbing, wine tasting, and baking bread.
