I research, write and teach on sexual ethics. I am particularly interested in the intersection of sex and technology. I am also interested in LGBTQ issues, alternative sexual identities, and issues relating to the rights of sexual minorities. I recently published a book, The Ethics of Sex: An Introduction. You can buy it here or here.

This book systematically and comprehensively examines the ethical issues surrounding the concept of sex . . . . Each chapter is rich in breadth and depth of discussion, especially the chapter on consent . . . The book would be ideal as a textbook for courses on sexual ethics. Recommended. Lower-division undergraduates through faculty; professionals; general readers.

I am also a specialist in the history of early modern philosophy. I am the author of the book David Hume’s Political Theory, the co-editor of David Hume’s Essays and Treatises, and the author of numerous articles and chapters on early modern philosophy. I recently published an article on Locke and sexual liberty.
