Douglas Geers is a composer who uses technology in nearly all his works, whether in the compositional process, as part of their sonic realization, or both. He has created concert music, installation works, and several large multimedia theater works. He also performs as an improviser, playing laptop and his own custom electronic instruments.

Reviewers have described Geers’ music as "glitchy... keening... scrabbling... contemplative" (New York Times), "kaleidoscopic" (Washington Post), "fascinating...virtuosic...beautifully eerie" (Montpelier Times-Argus), "Powerful" (Neue Zuericher Zietung), "arresting... extraordinarily gratifying" (TheaterScene.net), and have praised its "virtuosic exuberance" (Computer Music Journal) and "shimmering electronic textures" (Village Voice.)

Geers is a Professor of Music at Brooklyn College, a campus of the City University of New York (CUNY), where he is Director of the Center for Computer Music and the MFA program in Sonic Arts. He also serves on the Ph.D. composition faculty of the CUNY Graduate Center. Geers completed his DMA in Music Composition at Columbia University, where he studied with Tristan Murail, Fred Lerdahl, Brad Garton, and Jonathan D. Kramer.
