Daniel Sack holds a joint appointment in the Commonwealth Honors College and the English Department at UMass. He received his B.A. in English with a concentration in Creative Writing (Poetry) from Brandeis University and M.A./Ph.D. from Stanford University’s Drama Department where his research was funded by the Mellon Foundation and was awarded the Charles Lyons prize for distinguished dissertation. Prior to his appointment at UMass, he was an assistant professor of theatre studies at Florida State University and a Five College Mellon Postdoctoral Fellow.

Professor Sack's research traverses modern/contemporary drama and interdisciplinary performance more broadly conceived (theatre, dance, performance art, and the visual arts), performance theory and dramatic theory, and critical writing as a creative practice. He is the author of After Live: Possibility, Potentiality, and the Future of Performance (University of Michigan Press, 2015), which explores how live events stage encounters with the future as it becomes present; a short book on Samuel Beckett's Krapp's Last Tape (Fourth Wall Series, Routledge, 2016); and he is the editor of Imagined Theatres: Writing for a Theoretical Stage (Routledge, 2017), which gathers together short imaginary theatrical texts written by nearly 100 artists and scholars. His writings on contemporary international performance have been published in Theatre Journal, Studies in Theatre and Performance, PAJ: A Journal of Performance and Art, Yale's Theater, TDR: The Drama Review, HowlRound, and American Theatre, among others, and are included in a number of essay collections.
