Craig D. Marker, Ph.D. is the Chair of the Psychology Graduate Department at Keiser University and Founder  and co-director of the Anxiety Treatment Clinic.

His research focuses on how people with anxiety view their world.  For example, he uses eye-tracking methodology and psychophysiological methods to see how people react to an audience when giving a speech.  Previous research indicates that people with social anxiety have more initial and maintained focus on people with expressions of discontent, which leads to higher psychophysiological arousal.  These studies are leading to new and improved ways to treat social anxiety (as well as the other disorders completed in the Marker Lab).
