Current appointments:

Research Investigator and Speech-Language Pathologist, NCRAR, VA Portland Healthcare System

Adjunct Assistant Professor, Speech & Hearing Sciences, Portland State University

Research interests:

Marianne Casilio, PhD CCC-SLP is a speech-language pathologist with over a decade of experience working with adults with neurogenic communication disorders. Her research program centers on leveraging tools from cognitive neuroscience and quantitative methods to develop brain-behavior models of word production, naturalistic language production, and language comprehension in aphasia secondary to stroke and neurodegenerative disease.

Research projects (Current and recently completed):

Exploring the Role of Central Auditory Processing in Spoken Language Comprehension in Aphasia after Stroke
VA RRDT CDA1 Award 2025-2027

Neural Correlates and Recovery of Naturalistic Language Production in Aphasia after Stroke
NIDCD F31 Award 2023-2024
