Biography

Dr. Castro is an Assistant Professor in the Department of Communicative Disorders and Sciences. She completed a B.A. in Psychology (with Honors) from the University of Colorado, Colorado Springs and completed a dual-title Ph.D. in Psychology (Cognitive) and Gerontology from the University of Kansas. She also completed a post-doctoral fellowship in Cognitive Aging at the Georgia Institute of Technology (NIA T32 AG000175) and a post-doctoral fellowship in Clinical Aphasiology at the University of Washington (NIDCD F32 DC017074).

Current Research

Successful word retrieval is critical to everyday communication. Word retrieval impairments are a pervasive symptom of aphasia, an early feature of Alzheimer’s disease and related dementias, and even a common complaint of typically aging adults.

Dr Castro’s research focuses on word retrieval in aging adults and adults with language impairments (e.g., aphasia, dementia), with a particular focus on how words are organized in memory. Her research uses behavioral studies and computational modeling
