Biography
Dr. Diaz-Asper is a cognitive neuropsychologist by training, with a background and interest in teaching about the brain and behavior and conducting clinical research. Prior to coming to Marymount University, she worked both as a clinician and researcher, completing two different post-doctoral internships, at Johns Hopkins Hospital and the National Institutes of Mental Health. During this time, she conducted neuropsychological evaluations of cognitively-impaired adults, and also designed and implemented a number of research studies.
Most recently, her research has focused on applying computational methods like natural language processing and machine learning to the speech of older people to predict cognitive decline and dementia. She has authored several articles and received grant funding from the National Institutes of Health and Rotary USA’s CART Fund for this work.
