Dr. Safiya Umoja Noble will speak on April 20 at 6 p.m. on her book, The Algorithms of Oppression: How Search Engines Reinforce Racism, a pointed critique of how Google and other search engines marginalize people in “erroneous, stereotypical, or even pornographic ways.”

A professor at the USC Annenberg School for Communication and Journalism, she argues that Google and other Silicon Valley behemoths must be held accountable.

The event will be held in the Henry Madden Library as part of the J. Printise Womack Lecture Series.
