My research interests, which originate in philosophy of science and epistemology, are oriented towards emerging debates in the sciences of intelligent systems. With a focus on foundational issues, developments in cognitive science and artificial intelligence are examined from a philosophical lens. Such investigations, in turn, serve to constrain normative theorizing about learning, reasoning, knowledge and action. Identifying problems and formulating philosophical principles in these pursuits are guided by an overarching agenda of evaluating characterizations and explanations of rationality and intelligent behaviour.
