Tomás is the former Associate Director for Creativity & Culture at the Rockefeller Foundation. His work with the foundation included the Humanities Residency Fellowship Program, The Recovering and Reinventing Cultures Through Museums Program, The U.S. Mexico Fund For Culture, and Partnerships Affirming Community Transformation (PACT). Prior to joining the Rockefeller Foundation, Tomás was a tenured professor at Stanford University in the Department of Spanish and Portuguese. He has served as the Chair of the Mexican Museum in San Francisco and the Smithsonian Council, and has written and published extensively, focusing—for the most part—on Latin American and U.S./Latino cultural issues.
Tomás’s outstanding contributions have been widely recognized. To name a few, in 1998, he was awarded the Henry Medal by the Smithsonian Institution. In 2007 the Mexican Government bestowed “the Order of the Aztec Eagle” on Tomás for his lifetime achievement in building mutual understanding between Mexico and the United States through the art and humanities.
