Hammond's work is composed of myriad layers of media, ideas and associations. The process of piecing together an image is a meditative exercise for Hammond, having "more to do with duration than texture. I see it as a function of time, like the idea of chanting."

Her work is included in major American and international collections and she was the subject of a mid-career retrospective curated by the Cleveland Center for Contemporary Art that traveled to The Contemporary Museum, Honolulu, Hawaii; Madison Art Center, Madison, Wisconsin; and Blaffer Gallery, The Art Museum of the University of Houston, Texas.
