major 25-year retrospective of Viola's work. Viola was the 1998, Getty Scholar-in-residence at the Getty Research Institute, Los Angeles . Later, in 2000, he was elected to the American Academy of Arts and Sciences. In 2002, he completed Going Forth By Day, a digital "fresco" cycle in High-Definition video, commissioned by the Deutsche Guggenheim Berlin and the Guggenheim Museum, New York. In 2003,The Passions was exhibited in Los Angeles, London, Madrid, and Canberra. This was a major collection of Viola's emotionally charged, slow-motion works inspired by traditions within Renaissance devotional painting. The first biography of Viola, entitled Viola on Vídeo, was written by Federico Utrera (King Juan Carlos University) and published in Spain in 2011.

She has worked with Viola since 1978 managing and assisting Viola with his videotapes and installations. She documents their work in progress on location.
