I am an Associate Professor and Chair of the Undergraduate Program in Philosophy at the University of Pennsylvania. I research epistemology (including traditional, formal, and social epistemology), the nature of normativity in ethics and epistemology, and social philosophy with an emphasis on diversity and polarization.
I have a secondary appointment as an Associate Professor of Legal Studies and Business Ethics in the Wharton School of Business. During the Spring quarter of 2018, I was a Fellow of the Dartmouth Institute for Cross Disciplinary Engagement.
A large part of my research is about what we should believe. I recently finished writing book titled Right Belief and True Belief that’s under contract with Oxford University Press. The book argues for a general truth-loving epistemic consequentialist theory of what we should believe. The view says we should believe (but also set up groups, use decision-making procedures, arrange access to schooling, etc.) so as to promote having more true belief.
Another large part of my my research is about diversity and its effects on group deliberation and problem-solving. Most of this research is done with the Computational Social Philosophy Lab, an interdisciplinary and international research group that takes an empirically-informed approach to using agent-based computer models to investigate questions in social epistemology, political philosophy, and philosophy of science. Most of the group’s work focuses on topics like diversity and polarization in groups, the nature of expertise, how the structure of groups (like scientific lab groups) affects what information the group receives, how democracies can improve or hinder information flow, and how groups like juries can be better constructed to achieve their aims.
Before coming to Penn, I did a Ph.D. in Philosophy at the University of Michigan. I started at Penn as an Assistant Professor in January of 2013, and I received tenure and a promotion to Associate Professor in July 2019.
When I’m not working, I like to run and take pictures of birds .
