Aphasia Research Treatment Lab: People


Henry_Maya_lab director

Maya Henry, Ph.D., CCC-SLP

Lab Director

Dr. Henry is a speech-language pathologist by training. She did her master's and doctoral work at the University of Arizona, in the lab of Dr. Pelagie Beeson. Subsequently, she completed postdoctoral training in the lab of Dr. Maria Luisa Gorno-Tempini at the UCSF Memory and Aging Center. Her research interests lie in the nature and treatment of aphasia and related neurogenic communication disorders, with a special focus on primary progressive aphasia.

Heather Dial, Ph.D.

Postdoctoral Fellow

Dr. Dial received her B.S. in Psychology from the University of Houston (2010, Summa Cum Laude with University Honors and Honors in Major) and her PhD in Psychology from Rice University (2016) working under the guidance of Dr. Randi Martin. In her graduate research, she investigated models of speech perception and phonological short-term memory using evidence from behavior, eye-tracking, and structural neuroimaging in individuals with stroke-induced aphasia. Her current research interests lie in developing effective behavioral treatments for individuals with primary progressive aphasia and defining the neural bases of treatment-induced gains.

Eduardo Europa

Eduardo Europa, Ph.D., CCC-SLP

Postdoctoral Fellow

Dr. Europa has a BA with high honors in Cognitive Science from UC Berkeley, and received a MA and PhD in Communication Sciences and Disorders from Northwestern University under the guidance of Dr. Cynthia K. Thompson. His research interests include the neurobiological mechanisms of language processing, as well as longitudinal and treatment-induced neural and behavioral changes in primary progressive aphasia.

Graduate Students, Clinical Fellows and Research Staff

Stephanie Grasso's portrait

Stephanie Grasso, M.A., CCC-SLP

Doctoral Student

Stephanie Grasso graduated with a B.A. in Communicative Disorders from the University of Redlands, and a M.A. in Communication Sciences and Disorders from the University of Texas at Austin. Her research focuses on the nature and treatment of bilingual aphasia caused by stroke or neurodegenerative disease. In addition, she uses neuroimaging techniques to inform variability in treatment responsiveness in these populations.

Kristin Shaffer

Kristin Schaffer, M.S., CCC-SLP

Doctoral Student/Research Speech-Language Pathologist

Kristin earned a B.A. in Communication Sciences and Disorders from the University of Florida and a M.S. in Speech-Language Pathology from Vanderbilt University. Prior to joining the Aphasia Research and Treatment Lab, Kristin worked for several years in a variety of clinical settings including home health, rehabilitation centers, and private practice. These experiences shaped her research interests, which include assessment and multimodal treatment of aphasia resulting from neurodegenerative disease or stroke. Kristin is also interested in investigating the interaction between language and cognition and how that may inform clinical management of individuals with neurogenic communication disorders.

LIsa Wauters M.A. CCC-SLP, Research Speech Language Pathologist

Lisa Wauters, M.A. CCC-SLP

Research Speech-Language Pathologist

Lisa Wauters earned a Bachelor's degree in English and linguistics from Boston University and a Master's degree in speech-language pathology from the University of Texas at Austin. Her research interests include cognitive and communicative sequelae of traumatic brain injury, brain damage in bilingual populations and the treatment of speech and language disorders as the result of neurodegeneration, brain injury or stroke. Lisa is a credentialed speech-language pathologist and has provided services in several clinical settings, including a rehabilitation hospital, private practice and home health.

Carly Miller, M.S., CCC-SLP

Research Speech-Language Pathologist

Carly earned a B.S. in Communication Sciences and Disorders from The University of Texas at Austin and a M.S. in Speech-Language Pathology from Texas Christian University. Prior to joining the Aphasia Research and Treatment Lab in 2019, she worked clinically at a post-acute rehabilitation center for patients with traumatic and acquired brain injuries. Carly is currently based out of the Memory and Aging Center at the University of California, San Francisco. Her research interests include investigating treatments for aphasia and alexia caused by stroke or neurodegenerative disease.

Greg research coordinator

Gregory Jebaily, M.M.

Research Coordinator

Greg is a second-year Graduate Student Clinician in Speech and Language Pathology. He graduated from the University of Cincinnati with a Master's Degree in Vocal Performance and recently completed the leveling program at The University of Texas at Austin. Greg's research and clinical interests include the study and treatment of adults with acquired communication disorders - specifically, aphasia caused by stroke or neurodegenerative diseases. Additionally, Greg is interested in the treatment of motor speech and voice disorders.

Willa Keegan-Rodewald

Research Coordinator

Willa is a second-year graduate student in Speech-Language Pathology at the University of Texas at Austin. She graduated with a B.A. in Psychology from Lewis and Clark College. Her research and clinical interests include treatment for adults with acquired cognitive communication disorders, as well as treatment for bilingual speakers with developmental language disorders and acquired communication disorders.

Ariane Welch

Ariane Welch, M.S.

Clinical Fellow

Ariane Welch is a clinical fellow in speech-language pathology. She has a Masters in Speech-Language Pathology and a Bachelor of Arts (Hons & University Medal) in Semiotics from the University of Sydney, Australia. Her research interests include motor speech disorders and the treatment of Primary Progressive Aphasia via transcranial direct current stimulation (tDCS).

Karinne Berstisk

Karinne Berstis

Graduate Research Assistant

Karinne is a first-year graduate student in the Speech-Language Pathology program. She earned a B.S. in Radio-Television-Film from UT Austin in 2010, and returned to UT for the SLP leveling program in 2016. Her research interests include neuroimaging and investigating the etiology and effectiveness of treatment of neurogenic speech disorders.
