Director, Speech and Language Recovery Laboratory
Marja-Liisa Mailend, PhD
Bio

Dr. Mailend’s research focuses on speech and language production in various neurogenic communication disorders and in healthy speakers with a specialization in impairments of phonological encoding and speech motor planning. Her work has two primary directions. One arm of her research agenda focuses on the study of the underlying impairment in apraxia of speech and aphasia in the context of theoretical models of typical speech production. The second arm is dedicated to the development of theoretically-driven assessments and treatment approaches for remediating speech-language impairments. Her work combines different methodological approaches including behavioral speech and language assessments, acoustic analysis, psycholinguistic reaction time studies, and neuroimaging.

Dr. Mailend completed clinical training in speech-language pathology with a Master’s degree from the University of Tartu, Estonia and earned a doctorate in speech, language, and hearing sciences from the University of Arizona. Her research has been funded by the National Institutes of Health and the Albert Einstein Society (Einstein Healthcare Network, Philadelphia, PA).

 

Research Interests
  • Underlying mechanism of speech motor planning and speech motor planning impairments
  • Differential diagnosis of aphasia and apraxia of speech
  • Possible subtypes of apraxia of speech
