Tyler plays Dr. Tara Lewis, a forensic psychologist whose expertise is studying and interviewing serial killers after they're captured to determine if they're able to stand trial. She made her first appearance on "Criminal Minds" in the Season 11 premiere in 2015, and recurred in 19 episodes through the season.
Tyler's permanent gig on "Criminal Minds" will not impact her role on CBS's daytime talker "The Talk." Geller confirmed at TCA that Tyler will juggle both roles, like Julie Chen does with "The Talk" and "Big Brother."
