Brian Hedden received his A.B. in Philosophy from Princeton in 2006 and his PhD in Philosophy from the Massachusetts Institute of Technology in 2012. Before arriving at ANU, he was a Junior Research Fellow at Oxford (2012-2014) and a permanent staff member at the University of Sydney (2015-2020). He is the author of Reasons without Persons (OUP, 2015), as well as articles in Mind, Journal of Philosophy, Ethics, Analysis, Nous, and elsewhere. He has so far been awarded two major competitive grants from the Australian Research Council: a Discovery Early Career Researcher Award (DECRA) and a Discovery Project (DP), the latter joint with Mark Colyvan.

Brian Hedden’s research focuses primarily on the nature of rationality, including rational belief-formation and rational decision-making. There, he has written on time-slice-centric conceptions of rationality, the debate over evidential and causal decision theories, hindsight bias, Dutch Book arguments, and the objectivity of evidential support. He also works on related areas of ethics and political philosophy, including collective action problems, algorithmic fairness, and legal evidence.
