"[11] Cooper is an associate professor at West Chester University[12] and previously served on the faculty at Amherst College.
[13] Cooper's largest projects include Silver Threads, a song cycle for voice and electronic track released by Nonesuch Records,[14] and Ripple the Sky, a work for voice and processed string octet commissioned by the Los Angeles Philharmonic Association.
[15] These works highlight Cooper's focus on slow development and the stretching of musical time.
