Since 1976 has served as Founder/Artistic Director of the Social and Public Art Resource Center (SPARC) in Los Angeles, California and as Professor of Fine Arts for the University of California since 1980. She is currently serving as Vice Chair of UCLA's Cesar Chavez Center and Professor for UCLA's World Arts and Cultures department.

As a visual artist and one of the nation's leading muralists, Judith Francisca Baca is best known for her large-scale public art works. In her internationally reknowned Great Wall of Los Angeles, a landmark pictorial representation of the history of ethnic peoples of California from their origins to the 1950's, Baca and her teams of approximately 700 people produced 2,470 ft. of mural in segments over five summers from 1974 to 1984. The Great Wall engaged over 400 young people from 14-21yrs of age of diverse cultural and economic backgrounds working with countless scholars, oral historians, local artists, and hundreds of community members, making it one of the most monumental projects in the country dealing with interracial relations. Its half-mile length in the Tujunga Flood Control Channel, and the accompanying bike trails and park in the San Fernando Valley, hosts thousands of visitors every year, providing a vibrant and lasting tribute to California and the people who have shaped this country's history.

Baca founded the first City of Los Angeles Mural Program in 1974, which produced over 400 murals and hired thousands of local participants in its' ten years of operation. In 1976 she founded the Social and Public Art Resource Center (SPARC) in Venice, California, where she still serves as the Artistic Director. In 1988, at the request of Mayor Tom Bradley, she developed a new City of Los Angeles Mural Program, based on the successful model of the Great Wall of Los Angeles. This mural program, entitled "Great Walls Unlimited: Neighborhood Pride Program," has produced over 80 murals in almost every ethnic community in Los Angeles, training hundreds of artists and youth, and making it one of the country's most respected mural programs.

Baca's most recent works include commissions for:

University of Southern California: La Memoria De Nuestra Tierra, a 10ft by 30ft canvas mural.

The Baldwin Park Metrolink Station: Danza Indigenas, a 400ft colored concrete and brass designed train platform in five languages, including metate benches with shelters and 100ft plaza with 20ft four-directional arch.

From Pieces of Stardust, a 70ft interior mural for the Southern California Gas Company's new Los Angeles headquarters lobby.

Currently, Baca is working on a 50-ft digital mural commission for the central terminal of Denver International Airport. Also in progress is her on-going international collaboration on the WORLD WALL: A Vision of the Future without Fear. 10 foot by 30 foot portable mural panels on canvas make up this 210-foot mural in seven parts, addressing contemporary issues of global importance, war, peace, cooperation, interdependence, and transformation. As the WORLD WALL tours the world, seven additional panels by artists from seven countries will be added to complete this visual tribute to the "Global Village."

Baca has exhibited internationally and nationally. Her work appears in the museum collections of the National Museum of American Art at the Smithsonian and at the Wadsworth Atheneum in Hartford Connecticut.

The core of both her public and personal work are based on the belief that art is a tool for social change and self transformation, even fostering civic dialogue in the most uncivil places.
