Professor Emeritus



Ph.D., University of Mississippi, 1990

Research Interests

My research focus is on increasing the understanding of Central Nervous System mechanisms related to cognition seen in aging, aging pathology, and traumatic brain injury. This is accomplished through the use of traditional neuropsychological paradigms, structural and functional magnetic resonance brain imaging (MRI/fMRI), and cognitive intervention. Special foci of this work include geriatric aging and functional independence, aging psychopathology, concussive injury, and evaluation of data validity.

Neuropsychology and Memory Assessment Laboratory

The Neuropsychology and Memory Assessment Laboratory is no longer actively collecting data but maintains several large databases on the following: Normal and pathological aging; concussive injury; older adult caregiver/care recipient interactions; and neuroimaging reliability and validation. Databases typically include cognitive testing, structural and functional neuroimaging, personality variables, and daily function measures.

Please contact Dr. Miller directly ( for information about obtaining access to any of these databases.

Research Interests:

Brain imagingCognition, Aging, and Functional Independence: Our work  has been directed at understanding the inter-related processes of cognition, brain function/dysfunction, and functional independence as we age. In particular, we've studied how cognitive ability and brain function impact functional independence and community tenure. Studies have focused on: assessment of executive function and instrumental activities of daily living in community-dwelling elders; functional brain changes in mild cognitive impairment; influence of APOE on aging factors; impact of cognitive interventions on functional independence; and impact of driving training on cognitive abilities. 

Mild concussive injury and cognitive change: Our laboratory has also been interested in 1) the impact of concussive (mTBI) injury at acute periods and again in later life on neurocognitive and bioimaging measures, and to gauge the relative plasticity involved in cognitive function following acute and post-acute injury.

Research opportunities: As Dr. Miller is now retired from the University of Georgia, there are no current research opportunities for Graduate study nor undergraduate projects. Nevertheless, the Psychology department views these kinds of laboratory experiences as integral to the Psychology major and we encourage all UGA Psychology students to become involved in the many exciting research projects within the Department. Please visit the Department webpage for more information.
