About Me


My main research areas are philosophy of mind, philosophy of psychology, and philosophy of psychiatry. I explore philosophical and psychological questions about belief, imagination, delusion, rationality/irrationality, and normality/abnormality. 

I am an associate professor of philosophy at Hokkaido University. Previously, I was an associate professor at Hiroshima University, a research fellow at University of Birmingham as well as Keio University, a visiting student at Yale and MIT, and a graduate student at University of Tokyo.

I am an editorial member of Ergo, Philosophical Psychology, and the blog Imperfect Cognitions.
