I am a philosopher at the University of Pennsylvania—in title, Professor of Philosophy. Starting in July 2025, I will be director of Penn’s Visual Studies program. In June 2013 I completed my PhD in philosophy at Princeton University. I was advised by Michael Smith and Thomas Kelly. My Erdős number is 5. For more on my academic heritage, see this page.

​Prior to starting at Penn, I was a post-doctoral researcher at Franklin & Marshall College. ​Before coming to Princeton, I received an MA from the philosophy department at the University of Nebraska-Lincoln. Before going to the Great Plains, I graduated from Arizona State University with Bachelor of Arts degrees in philosophy and political science. In the 21-22 AY I was a Laurance S. Rockefeller Visiting Faculty Fellow at the University Center for Human Values at Princeton University. I was also a Marc Sanders Foundation Philosophy in the Media Fellow that AY. For information about my interests in public philosophy, see the In the Wild page. ​During the 17-18 AY I was a Marie S. Curie FCFP Junior Fellow at the Freiburg Institute for Advanced Studies at the Albert-Ludwig-Universität Freiburg

My main interests are in ethical theory, epistemology, aesthetics, and the philosophy of perception. Issues in metaphysics and the philosophy of mind are also intimately connected to my work.

My first monograph is a systematic defense of the claim that what it is to be rational is to correctly respond to the normative reasons you possess. It came out in 2018 with Oxford University Press. In 2016 Oxford University Press published Weighing Reasons, a collection I co-edited with Barry Maguire. I am currently writing a book about the connections between the epistemology of ethics, the epistemology of aesthetics, and the philosophy of perception. For more information on all three books, see the book page.
