Current Projects

  1. Registry and Repository. Research subject pool and database for individuals with acquired neurogenic communication disorders (e.g., aphasia, apraxia of speech, cognitive-communication disorders) stemming from stroke, TBI, and other neurological diseases and disorders. Actively recruiting.
  2. Repetition Priming. The purpose of this investigation is to determine optimal dosage for intensive naming therapy for stroke survivors who have anomia (i.e., word finding deficits). Stroke survivors with aphasia name pictures multiple times per session for 2-3 sessions per week for up to 5 weeks. Actively recruiting.
  3. Communicative Participation Item Bank. The purpose of this investigation is to determine the reliability of a standardized measure of communicative participation between stroke survivors with aphasia and their proxies (i.e., caregivers, spouses, etc.). Actively recruiting.
  4. Reaching Rural Montana: Developing a Telepractice Program for Speech-Language Pathologists


As Director of the Big Sky Aphasia Laboratory at the University of Montana, Catherine’s team investigates principles of neuroplasticity as they relate to the rehabilitation of neurogenic communication disorders stemming from stroke and traumatic brain injury in the context of the World Health Organization International Classification of Functioning, Disability, and Health (WHO-ICF) model.
