Biography

Diana Petroi, Ph.D. joined the Communication Sciences and Disorders faculty as part of the recently launched master’s program. She is a clinician-researcher and professor, with areas of expertise in neurologically-based motor speech and language disorders, cognitive-communicative impairments and dysphagia. Her clinical and research interests include differential diagnosis and understanding brain-behavior relationships of motor speech/language disorders, comparing clinical findings across various domains and collaborating across disciplines for teaching, research and quality care purposes. She earned a bachelor’s degree in communication disorders from Biola University, a master’s degree in speech-language pathology from Loma Linda University, and a doctorate in communication sciences and disorders from Texas Tech University Health Sciences Center. She also completed a Postdoctoral Fellowship in the Department of Neurology, Division of Speech Pathology, at Mayo Clinic in Rochester, Minn. Petroi’s clinical practice has focused on medical speech-language pathology, with her providing direct patient care to persons with medical issues resulting in various communication and swallowing disorders. She also has experience working with speech-language pathology and medical students and residents, being part of multidisciplinary care teams, serving on national professional committees and presenting at local, state and national meetings and conferences.
