Research

Recently, I have been developing a new way of thinking about the value of species. I argue that nature's "irreplaceable designs" are a locus of final value. This approach delivers similar results to a species-centered account in many cases, but it is able to avoid some significant theoretical obstacles, and delivers better results in situations where the two diverge. At the moment, I'm focused on shoring up the theory itself and exploring its applications, especially in conservation biology.

I also work on issues at the intersection of metaethics and moral psychology, including normative skepticism, the evolution of morality, and the relationship between normative judgment and motivation.
