New York-based artist and educator Mark Tribe has been appointed the chair of the graduate fine arts department at New York's School of Visual Arts. He replaces founding chair David L. Shirey, who is retiring after 30 years in the post, effective July 1.

"Mark has proven himself an innovator in the truest sense of the term," SVA president David Rhodes said in an e-mail announcing Tribe's appointment.

Tribe has been on the faculty in the school's art practice department since 2011, and has taught at Brown University, in Providence, R.I., Columbia University's School of the Arts, New York, and Williams College, Williamstown, Mass. Tribe is also widely known as the founder of Rhizome, an organization that supports the creation, presentation and preservation of artistic practices that involve technology.

Tribe's own artworks often deal with social and political issues. His "Port Huron Project" (2006-09), for example, consisted of a series of reenactments of Vietnam-era protest speeches, presented in gallery settings via video documentation.
