Brett Karlan received his Ph.D. in Philosophy from Princeton University, where he wrote a dissertation on rationality, reasoning, and human bias. He works at the intersection of normative philosophy (especially epistemology and ethics) and the philosophy of science (especially cognitive science and AI). For the past two years, he has been a research fellow in the History and Philosophy of Science Department at the University of Pittsburgh, where he worked with Colin Allen on the Machine Wisdom Project. His current research focuses on how notions like rationality, reasons-responsiveness, and achievement might help us construct robust frameworks for understanding the intersection of cognition, action, and emerging technology. Brett will join the Center as an Interdisciplinary Ethics Fellow in partnership with HAI.
