My primary research concerns the epistemology of inquiry. For instance, I am interested in what kinds of reasons and values researchers should be sensitive to, and what attitude it is rational to have toward one's favored theory during inquiry. I argue that it is often irrational to believe one's favored theory; instead, the appropriate attitude is one that I call endorsement. This attitude is governed by a set of norms I call inclusive epistemic rationality, which is sensitive to considerations of what will promote successful inquiry. I also have a research project building on my published work involving virtue epistemology and reliabilism. In addition, I am working on projects involving fragmentation of mental states, collective epistemic responsibility, and the epistemology and ethics of data and technology.
