Marjorie Nicholas, PhD, CCC-SLP
Director and Clinical Supervisor

Marjorie Nicholas worked as a speech-language pathologist for over 15 years at the VA Boston Healthcare System. In 2001 she joined the Institute faculty, founded the Aphasia Center, and is currently a professor and chair of the CSD department, and associate director of the PhD in Rehabilitation Sciences.

She has co-authored research articles on aphasia, language in normal aging, and dementia and is the co-author of various assessment and treatment materials for aphasia including the Boston Assessment of Severe Aphasia (BASA), the Sentence Production Program for Aphasia (SPPA), and the C-Speak Aphasia software program.

Her research interests focus on the treatment of severe aphasia, and in particular on the cognitive and neuroanatomical mechanisms underlying successful use of augmentative and alternative communication systems by people with aphasia.

She also conducts research on nonverbal cognition in people with aphasia and on the relation between cognitive and linguistic impairments to quality of life in people with aphasia.

Marjorie received her training in aphasia assessment and treatment while working at the Boston VA under the mentorship of Harold Goodglass, Martin Albert, and Nancy Helm-Estabrooks.
