Dr. Beevers' primary research interest focuses on the cognitive etiology and treatment of major unipolar depression. His research has examined whether depression vulnerability is associated with negatively biased attention, thought suppression, and poor cognitive change during treatment. Dr. Beevers is particularly interested in the interplay between biology (e.g., variants of the serotonin transporter gene), cognitive risk factors for depression, and reactivity to transient mood states. Finally, he is interested in whether treatments modify putative risk factors for depression.
