Lee Ryan completed her undergraduate work at University of Toronto,
received a Ph.D. in Cognitive and Clinical Psychology at the University
of British Columbia in 1992, and completed a postdoctoral fellowship
at the University of California at San Diego. Currently she is the Director
of the Cognition and Neuroimaging Laboratory at the University
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.
an associate professor in the Cognition and Neural Systems program
and the Clinical Neuropsychology program at the University of Arizona's
Department of Psychology, Dr. Ryan teaches undergraduate classes
in human memory and graduate level courses such as Human Brain Behavior
Relationships, Cognitive Neuroscience, and Principles of Neuroanatomy.
As a clinical psychologist, Dr. Ryan works with individuals and
families who are coping with chronic and progressive diseases that
effect cognitive functioning, including multiple sclerosis, Parkinson's
disease, and Alzheimer's disease.
