Biography

Aimee Dietz, Ph.D. serves as the chair of the Department of Communication Sciences & Disorders. By training, she is a speech-language pathologist (SLP) who has dedicated her career to improving outcomes for people with aphasia—first as a clinician, then as a clinical researcher. She earned her bachelor’s and master’s degrees from Florida State University. During her clinical work, Dietz quickly learned that rehabilitation for people with aphasia is grossly limiting.

She reports, “During inpatient and outpatient rehabilitation we work hard to restore lost language functions and when the person ‘plateaus’ in their recovery, augmentative and alternative communication (AAC) is provided to help them communicate — leaving them to feel as if therapists have given up on them and that recovery has ended.”

For these reasons, she completed her Ph.D. under the direction of Drs. David Beukelman and Karen Hux at the University of Nebraska-Lincoln, with a focus on understanding the unique considerations involved in the development of AAC interface designs for people with aphasia.

During her time at the University of Cincinnati (2008-2021), Dietz forged a line of research examining the role of AAC as a language recovery tool for people with chronic aphasia, using neuroimaging technologies to identify neurobiomarkers for AAC-induced language recovery. This work continues at Georgia State, with an added emphasis of understanding how AAC can be successfully administered to people with aphasia via teletherapy — and during the subacute stages of post-stroke recovery.

In recent years, she has cultivated a new line of research that seeks to understand how mind-body practices, including adapted yoga, might be harnessed to build resilience and coping for people with post-stroke aphasia and their co-survivors. In this work, she collaborates with Lauren Bislick, Ph.D. at the University of Central Florida and E. Susan Duncan, Ph.D. at Louisiana State University. Together they work alongside SLP Stephanie Van Allan, survivor and yogi, J. Chase Rushlow and co-survivor and yogini, Deanna Rushlow. The self-dubbed, Team Yoga met at Project BRIDGE (a PCORI-funded conference to bring together research-clinician-patient stakeholders) in 2018 and work alongside clinician, patient and caregiver stakeholders.

In 2020, Dietz completed her 200 hour Registered Yoga Teacher training to help advance this line of inquiry. Team Yoga pursues their work in honor of Terri Kersey, who first helped launch the idea of integrating yoga into stroke rehabilitation before her unexpected death in 2019.

Dietz is also the director of the Language Recovery & Communication Technology Lab and routinely supports student researchers with projects funded by various foundations, the National Institutes of Health (NIH) via the National Institute of Deafness & Other Communication Disorders (NIDCD) and the American Speech-Language-Hearing Association (ASHA).

Over the years, Dietz has mentored more than 50 students, including the advising of summer undergraduate students through various programs such as McNair, University Honors Program and Women in Science and Engineering (WISE). She also enjoys mentoring Ph.D. students, post-doctoral students, as well as junior faculty. She actively pursues opportunities to enhance her mentoring skills through University-level programs, as well as through participation in programs via the American Speech-Language-Hearing Association (ASHA), such as Pathways and Mentoring Academic Research Career (MARC).
