Mariusz Kozak is the author of Enacting Musical Time: The Bodily Experience of New Music (Oxford University Press), in which he examines how listeners' understanding and experience of musical time are shaped by bodily actions and gestures. His research centers on the relationship between music, cognition, and the body. Kozak bridges experimental approaches from embodied cognition with phenomenology and music analysis, in particular using motion-capture technology to study the movements of performers and listeners. His articles have appeared in the Journal of Music Theory, Music Theory Spectrum, and Music Theory Online, among others. In 2020 he was one of the featured speakers at the Plenary Session of the Annual Meeting of the Society for Music Theory. In 2022 his article "Feeling Meter: Kinesthetic Knowledge and the Case of Progressive Metal" (Journal of Music Theory) won the Society for Music Theory Popular Music Interest Group Outstanding Publication Award. He is currently writing a book on the cultural and intellectual history of the cognitive science of music.
Kozak is on the Steering Committee for the Columbia College major in Cognitive Science.
