My research specializations are in epistemology and ethics. In those areas I have published on the foundationalist-coherentist dispute, the work of Wilfrid Sellars, the justification of morality, computer ethics, and pedagogical issues relating to the teaching of ethics. I've written two books: Morality’s Critics and Defenders – A Philosophical Dialogue and, with colleague Bill deVries, Knowledge, Mind and the Given: Reading Wilfrid Sellars's “Empiricism and the Philosophy of Mind."
Outside of my areas of specialization, I have published in ancient philosophy, women's studies, the sociology of knowledge, metaphilosophy, and the philosophy of color perception.
I participate in the P4C (Philosophy for Children) movement, teaching philosophy in elementary, middle and high schools and working with teachers and education students to incorporate philosophical topics and discussions into their classrooms.
I am interested, both in terms of research and pedagogy, in furthering the idea of a common, universally shared morality.
