Research efforts focus on several areas, including neurocognition, intervention, and/or EEG applications. The lab has examined and continues to investigate for instance, the neurocognitive outcome of Obsessive-Compulsive Disorder and related spectrum disorders in addition to answering questions pertaining to both subjective and objective cognitive abilities/impairment; and, the evaluation of post-traumatic sequaelae in Traumatic Brain Injury, such as accident phobia, pain, and emotional distress.
