Museum moved into the newly completed Nelson Fine Arts Center, designed by architect Antoine Predock, where the museum remains today. The Nelson Center is and includes five galleries as well as administrative offices and storage and processing areas. Soon after the Art Museum's move to its new facility, the size of its staff doubled, and a curator of education, a print collection manager and several administrative and security workers were added to the staff. In 1992, Marilyn A. Zeitlin became the museum's director. Zeitlin was praised for expanding the museum's collections eightfold during her tenure. Under Zeitlin, the museum was chosen to curate video artist Bill Viola's show at the United States Pavilion at the Venice Biennale in 1995. However, the museum experienced controversy when The Arizona Republic revealed that a university audit in early 2007 showed that the museum had received $450,000 over seven years from prominent donor Stephane Janssen, one of the museum's largest donors, and arranged with him to buy art from Janssen's company. The arrangement was found to not be illegal but was discontinued. Zeitlin stepped down at the end of the year in 2007 after 15 years as director. There was "unanimous agreement that the ASU Art Museum has flourished" during Zeitlin's tenure. In March 2002, the Ceramics Research Center opened in the Tempe Center just to the north of the Nelson Center. The center was designed by Gabor Lorant Architects, Inc. and includes with two galleries, open storage stacks and a research library. Additional facilities at the library's two buildings include a lecture room, a print study room, and a "nymphaeum" (courtyard). Collections Works of contemporary art held by the museum include works by Hung Liu, Karel Appel, Derek Boshier, Deborah Butterfield, Sue Coe, Dan Collins, Vernon Fisher, Jon Haddock, William Kentridge, Lynn M. Randolph, Frances Whitehead, and William T. Wiley. The focus of ASU Art Museum's Latin American art holdings is on Mexican art from the 20th century, Mexican ceramics and folk art; and contemporary Cuban art. The core of the Latin American collection was donated to the museum in 1950 and includes works by David Alfaro Siqueiros, Diego Rivera, and Rufino Tamayo. Later acquisitions of pieces by Mexican artists include works by Carlos Mérida, Leonel Góngora, Rafael and Pedro Coronel; José Guadalupe Posada, Leopoldo Mendez, and other members of the Taller de Gráfica Popular; and the contemporary artists Alejandro Colunga, Lucio Muniain,
