Her sound poem I Come Out of Your Sleep (revised and recorded on Sinopah 1997 XI) is constructed from speech sounds in Louise Bogan's poem "Little Lobelia." According to the composer "a very soft dynamic level is an integral component of this piece. It is important to listen to it in the way it was composed, near the threshold of hearing." (liner notes) Her collage piece SUM (State of the Union Message) is incluced on the Lesbian American Composers collection (1998 CRI: 780).

"She has been the recipient of grants from the National Endowment for the Arts and New York State Council on the Arts as well as a Fulbright Award, to name but a few of the organizations who have recognized her formally."
