Dr. Roozbeh Behroozmand

Roozbeh Behroozmand, PhD

Associate Professor, Principal investigator

Roozbeh Behroozmand is an Associate Professor of Speech, Language, and Hearing and the Director of the Speech Neuroscience Lab in the School of Behavioral and Brain Sciences at The University of Texas at Dallas. Dr. Behroozmand has background in biomedical engineering and neuroscience and his research is focused on investigating the neural bases of speech production and motor control in the human brain. His lab utilizes a wide range of techniques including electrophysiology (EEG, ERP, ECoG), functional neuroimaging (fMRI), EEG-based neurofeedback training, and high-definition transcranial brain stimulation (HD-tES) to study sensory-motor mechanisms of speech in neurotypical adults and patients with neurological disorders. The ultimate goal of this research is to advance translational knowledge for the development of novel diagnosis and clinical treatment methods to enhance speech communication and improve quality of life in patients with speech disorders.

Kaylee Ray, MS, CCC-SLP

Speech Language Pathologist, Clinical Manager

Kaylee Ray is a Speech Language Pathologist and Clinical Manager at the Speech Neuroscience Lab in the School of Behavioral and Brain Sciences at The University of Texas at Dallas. She has years of clinical experience working with pediatric, adult and geriatric populations with a wide variety of deficits and diagnoses. She specializes in the diagnostics and treatment of cognition and language disorders in patients following brain injury, stroke or neurological decline. She also has skilled background in dysphagia, Fiberoptic Endoscopic Evaluation of Swallowing (FEES), alternative/augmentative communication and American Sign Language.

Post-doctoral Scholars

Vahid Nejati, PhD

Post-doctoral Scholar

Vahid Nejati is a cognitive neuroscientist specializing in cognitive and neurorehabilitation. He focuses on the remediation of brain functions by targeting cognitive processes and the associated cortical areas through cognitive training programs and non-invasive brain stimulation. His current focus is on discovering the sensory, motor, and cognitive underpinnings of language and the corresponding neural structures, with the goal of developing remediation programs for language and speech disorders.

Graduate Students

Yilun Zhang, MSc

Yilun Zhang, MSc

PhD Student

Yilun Zhang is a doctoral student in the Speech Neuroscience Lab in the Department of Speech, Language, and Hearing in the School of Behavioral and Brain Sciences at The University of Texas at Dallas. Yilun’s research focuses on understanding the role of cognitive mechanisms in the production and sensory-motor control of speech in neurotypical adults as well as stroke survivors with aphasia. For her research, Yilun uses advanced EEG signal analysis methods to examine the neurophysiological correlates of speech motor function and their impairment in clinical populations with post-stroke aphasia.

Mackenzie White, BSc

Master’s Student

Mackenzie is a Graduate Student at the University of Texas at Dallas. She is pursuing a Masters of Speech Language Pathology to be completed in Spring 2025. She is passionate about communication, connection, and helping others. Her career interests include adult cognition, aphasia, and dysphagia.

Undergraduate Students

Alyssa Su

Undergraduate Student

Alyssa is an undergraduate student majoring in Speech Language Hearing Sciences and Psychology at The University of Texas at Dallas. After graduating, she intends to pursue a master’s degree in Speech-Language Pathology. During her time in the Speech Neuroscience Lab, Alyssa hopes to learn more about neurological conditions that affect the fundamental neural structures underlying speech production.
