Since 2019 I have been a professor in the University Center for Human Values at Princeton, with appointments in the Religion and Philosophy departments.

Together with Lara Buchak, I direct the new Princeton Project in Philosophy and Religion. 

I’m also honored to be serving as the current president of the North American Kant Society.

From 2004 to 2016, I was assistant and then associate professor at Cornell’s Susan Linn Sage School of Philosophy, with affiliations in German Studies and Religious Studies.  From 2016-2017 I was a professor in the University of Pennsylvania Philosophy department.

My research focuses mostly on Immanuel Kant and other early modern philosophers, as well as on philosophy of religion, the ethics of belief, and certain issues in aesthetics and moral psychology (especially hope and despair). I am also developing a scholarly-activist interest in food ethics.  Here is my CV.

Hope, Despair, Optimism, Pessimism

Website for a 4-year, $5M cross-disciplinary grant effort, co-directed with Sam Newlands at Notre Dame. The main goal was to bring philosophers, psychologists, sociologists, scholars of religion, and even some theater- and film-makers together to think collaboratively about the nature and roles of hope and despair in human life.
