Curriculum Vitae

Research Interests

Owen Carmichael is Professor and Director of Biomedical Imaging at Pennington Biomedical Research Center in Baton Rouge, Louisiana. As Director of Biomedical Imaging, he oversees MRI, DXA, and ultrasound data collection and analysis at Pennington Biomedical. His laboratory works to develop new biomedical imaging techniques that can be applied to study Alzheimer’s disease, brain aging, metabolic disorders, and exercise, with an emphasis on the effects of lifestyle factors on the aging brain.

Dr. Carmichael is a Principal Investigator of National Institutes of Health-funded research studies that assess brain aging in the Bogalusa Heart Study, effects of exercise on brain health among older African Americans, and effects of exercise on skeletal muscle characteristics. He has also led or contributed to clinical trials assessing effects of pharmaceuticals and food products on the brain, using functional MRI as an outcome measure.
