Curriculum Vitae

Heather Dial received a Ph.D. in psychology from Rice University in 2016 and a B.S. in psychology from the University of Houston in 2010. From 2016-2021, she completed a postdoctoral fellowship in Speech, Language, and Hearing Sciences at The University of Texas at Austin. Her primary research interests are in the cognitive and neural processes supporting speech perception and language comprehension, with a focus on how these processes are impacted in stroke-induced and primary progressive aphasia. Outside of work, Professor Dial loves to watch cartoons, go camping, run, bike, listen to and play music, read and spend time with her friends, family, dogs and cats.

Research Interests

Professor Dial’s research interests relate to the cognitive and neural processes supporting speech perception and language comprehension. She has investigated cognitive and neural changes in speech and language processing in the context of stroke-induced and primary progressive aphasia, rehabilitation of speech and language processing in these populations, and the cognitive and neural processes supporting treatment-induced gains. Her research takes an interdisciplinary approach to bridge the gap between basic science and applied, clinical research and uses a wide variety of methods, including behavioral, eye-tracking, structural neuroimaging (voxel-based lesion symptom mapping, voxel-based morphometry), electroencephalography (EEG), natural language processing and machine learning.
