Research Interests

In epistemology/philosophy of science: skepticism, theories of justification and knowledge, epistemic consequentialism, epistemic values, entitlements, the problem of perceptual justification, theories of rationality, the problem of induction, theories of understanding.

In philosophy of language: various forms of double-index semantics, the semantics of questions, the semantics-pragmatics interface, hybrid expressivism and double-speech-act theories, predicates of personal taste and other terms that combine classificatory and evaluative aspects.

In aesthetics : the meaning of aesthetic judgments, the metaphysics of aesthetic properties, theories of art, the epistemic value of art.

My current and future work tries to combine these research interests in a fruitful way. For example, I am currently interested in the relation of theoretical and practical rationality in the aesthetic domain, the speech-act theoretic classification of aesthetic and art-critical assertions, the epistemic value of art, the relation of art and science, and the epistemology of aesthetic judgments. I am also interested in expanding my interdisciplinary collaborations with researchers from other disciplines, such as:  cognitive psychology, linguistics, art and cultural studies.
