Sarah Bay-Cheng is Associate Professor & Director of Graduate Studies in Theatre at UB, where she teaches courses in dramatic literature, contemporary theatre, theories of performance, and intermediality. Her research interests include avant-garde theatre and film, modernist literature and performance, performance poetics, sexuality in modern drama, and intersections of technology and theatre. Published books include Mama Dada: Gertrude Stein's Avant-Garde Theater (Routledge) and Poets at Play: An Anthology of Modernist Drama (Susquehanna UP), and she is currently co-editing a book on digital media and theatrical performance. Her essays and reviews on dramatic literature, performance theory, and media have appeared in Theatre Journal, Theatre Topics, Études Théâtrales/Essays in Theatre, and in several book collections, including Playing with Theory (Palgrave), The Companion to T.S. Eliot (Blackwell), The Companion to Twentieth Century Drama (Blackwell), Theater and Film (Yale), and Theater of the Avant-Garde (Yale), among others. Her current book project reviews the history of the performing body in the twentieth century.

Bay-Cheng is also a founding member of the Intermedia Performance Studio--an experimental performance collaboration integrating virtual reality, artificial intelligence, and live performance. The IPS has presented its work both nationally and internationally, and has received several grants for its projects. From 2005-2008, Bay-Cheng was jointly appointed with the Department of Media Study, and she is an affiliated faculty member in the Poetics Program through the Department of English at UB. She is a member of the international research group, Intermediality in Theatre & Performance, affiliated through the International Federation for Theatre Research (IFTR/FITR), and has served in elected positions for national organizations, such as the Association for Theatre in Higher Education (ATHE) and the American Theatre & Drama Society (ATDS). As a puppeteer and mask performer, Bay-Cheng has written several plays specifically for puppets performance, and these adaptations have appeared at both colleges and international venues, including her adaptations of Richard Wagner's ring cycle (2001) and Medea (2003). Her original play, "The Peacock Flew," was adapted for National Public Radio's Archaeology of Lost Voices Series (presented as "Hidden Dragon" 2001). Bay-Cheng received her A.B. in Theatre and Film from Wellesley College and her Ph.D. in Theatre from the University of Michigan.
