Ryo Tanaka

JSPS Postdoctoral Fellow, University of Tokyo

I am a JSPS postdoctoral researcher at University of Tokyo (History and Philosophy of Science Lab), Japan. My host researcher is Professor Naoya FUJIKAWA. My current research project is entitled, "Moral obligation to explicate semantic rules of one's language."

I obtained a Ph.D in philosophy at the University of Connecticut, U.S.A., in the Summer of 2021. My dissertation explores philosophical issues concerning lexical semantic knowledge and its expression in action (please see "research" page for more details). My current research project is an attempt to bring descriptive issues that I addressed in the dissertation into more practical, specifically, ethical, contexts.

I am an affliated member of the ECOM (Expression, Communication and the Origins of Meaning) research group at Uconn.

I did BA and MA in philosophy at Kyoto University, Japan. My master's thesis is on Wilfrid Sellars. During my MA studies, I also spent a semester as a research student at National University of Singapore.

My academic interests include philosophy of language (esp. foundational issues about meaning), philosophy of mind (esp. concepts and intentionality), action theory, epistemology, and meta-ethics (esp. semantics and pragmatics of normative language).

I also have interests in the history of philosophy, including Western early modern philosophy (esp. Locke, Hume and Kant), and the history of 'analytic' philosophy (esp. Frege, Logical positivism, Quine and Sellars).

My CV is available upon request.
