Dr. Ryan is an Assistant Professor in the Departments of Psychology and Neurology. Currently she is the Director of the Cognition and Neuroimaging Laboratory at the University of Arizona. Her research focuses on the neural basis of memory, age-related changes in memory, and how these changes relate to brain functioning. Her research is currently funded by the National Institute on Neurologic Disorders and Stroke, the Arizona Disease Control Research Commission, and the Arizona Alzheimer's Disease Research Center. She has a special interest in memory disorders such as Alzheimer's Disease, AIDS-related dementia, and diseases of white matter including multiple sclerosis.
