My primary research focus is the philosophy of Thomas Hobbes. My past work has examined topics such as the debate between Hobbes and Robert Boyle concerning experimentation and scientific knowledge, Hobbes’s objections to the Meditations, Hobbes’s view of the relationship between mathematics and physics, and Margaret Cavendish’s criticisms of Hobbes’s explanation of visual perception.


I also have research interests in the following topics in bioethics: the nature of physician obligations, issues surrounding organ transplantation, and informed consent.
