Research Interests (in no particular order):

Kant's Ethics

Kant's Doctrine of Virtue: A Guide (Oxford UP, 2021). This is a commentary on Kant's final work in ethics, The Doctrine of Virtue, Part II of the 1797 Metaphysics of Morals, in which he sets forth his normative ethical theory. 

Significance and System: Essays on Kant's Ethics (Oxford UP, 2017). This is a collection of some of my published work on Kant's ethics, including some I've co-authored with Houston Smit. 

Sorin Baiasu and I are editing a collection of 44 newly written essays by renowned scholars covering a vast range of topics from the entire Kantian corpus entitled The Kantian Mind to be published by Routledge Press.

Metaethics & Moral Phenomenology
In addition to my ongoing work on Kant's ethics, I continue to collaborate with Terry Horgan.  A Collection of our essays in metaethics entitled, Moral Twin Earth and BeyondMetaethical Meditations is under contract with Oxford University Press. 

Terry and I are recipients of a John Templeton Foundation Grant in support of our writing a book in progress, Illuminating Reasons: An Essay in Moral Phenomenology. This grant also supported a conference featuring eight talks and streamed live.   

Moral Epistemology
Aaron Zimmerman, Karen Jones, and I are editors of The Routledge Handbook of Moral Epistemology (2019) featuring 30+ commissioned essays covering topics that relate moral epistemology to science, normativity, and its applications. 

I organize the annual Arizona Workshop in Normative Ethics (WiNE) that takes place in Tucson each January. The 14th Workshop, January 19-21, 2022 will feature Sarah Stroud and Jamie Dreier as keynote speakers. The full program will be available in mid-July and will be posted on the workshop website which includes details about the workshop location, accommodations, and registration (which is free).  

A selection of papers from the Workshop is published in Oxford Studies in Normative Ethics. Volumes 1-11 are in print.
