Laboratory for Neurocognitive Research

Research and Teaching

Research Topics

Dr. Ettenhofer's Laboratory for Neurocognitive Research studies brain-behavior relationships after traumatic brain injury (TBI). The primary goal of this research is to identify factors related to outcome and recovery after TBI and to aid in the development of targeted treatments. Current studies focus upon the development of robust eye-tracking indicators of neurocognitive status to aid in management of TBI, and the use of virtual reality (VR) for assessment and remediation of driving abilities after TBI. Primary study populations include military personnel with combat-related TBI as well as civilians suffering from TBI related to sports, accidental injuries, and other causes. Previously, Dr. Ettenhofer has also conducted research examining neurocognition, neuroimaging, and functional abilities in HIV/AIDS, aging/dementia, and adult ADHD.

Current Grant Support

Department of Defense (DOD) Congressionally Directed Medical Research Program (CDMRP) Telemedicine and Advanced Technology Research Center (TATRC) Award; Center for Neuroscience and Regenerative Medicine (CNRM) - CNS Repair and Recovery Award.

Methods and Approach

Eye/gaze tracking; Virtual reality; Neuroimaging (i.e., MRI, DTI, fMRI); Electroencephalography (EEG); Neuropsychological assessment.

Medical Student Teaching

MPS Course Director for MS-I Training; MPS Module Director for MS-I Neuroscience & Behavior Training. Lectures on Psychological & Neuropsychological Assessment, Traumatic Brain Injury, and Behavioral/Mental Health.

Graduate Student Teaching

Research Methods I (MPO901) and Neuropsychology (MPO533). Lectures on Traumatic Brain Injury, Human Cognitive Neuroscience, Technology Development in Behavioral Medicine, Cognitive Remediation, and Health Psychology.


Dr. Ettenhofer currently mentors five psychology graduate students, two post-doctoral fellows, four research staff, and two volunteers in research activities. He also provides clinical mentorship to eight psychology graduate students.
