Research Interests:

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 Beyond is forthcoming from Oxford University Press. Terry and I are recipients of a John Templeton Foundation Grant that will support our writing a book, Illuminating Reasons: A Essay in Moral Phenomenology during the 2012-2013 academic year.

I organize the annual Arizona Workshop in Normative Ethics (WiNE) that takes place in Tucson each January.  The 5th Workshop, January 9-11, will feature Philip Pettit, Christine Swanton, and T. M. Scanlon as keynote speakers. The full program will be available mid-July and will be posted on the workshop homepage, which includes details about the workshop location, accommodations, and registration (which is free).  

A selection of papers from the Workshop is published by Oxford University Press.  
Oxford Studies in Normative Ethics, Volume Three featuring papers from the third workshop that took place in 2012 will be published fall, 2013.
