My work is in epistemology, and it focuses on defending a form of normative epistemology. In particular I've tried to address issues dealing with the structure of justification, skepticism and the definition of knowledge. I argue that the best accounts in each of the three areas are, respectively: infinitism, an anti-skeptical position, and a type of defeasibility account of knowledge. But in defending each view I try to accommodate the plausible aspects of the opposing views.
