Want to share your feedback? Send us a message!Dr. Shahriar SheikhBahaei, Assistant Professor of Neurobiology and Behavior at Stony Brook University, joins host Sara MacIntyre, M.A., CCC-SLP, to discuss emerging research exploring the cellular and neurobiological mechanisms underlying stuttering. Dr. SheikhBahaei shares his journey from lived experience with stuttering to leading a neuroscience research lab investigating how glial cells, particularly astrocytes, contribute to motor control and speech-related circuits.The conversation delves into several recent studies from his lab that utilize mouse models to uncover how alterations in astrocyte function and iron regulation may relate to the neural pathways involved in stuttering. Dr. SheikhBahaei walks listeners through the background, scientific rationale, and key findings of these studies, highlighting what they reveal about the non-vocal motor aspects of stuttering and how this basic science may inform future directions in understanding and treatment.The episode concludes with reflections on bridging laboratory research with the lived experiences of people who stutter and fostering collaboration among scientists, clinicians, and the stuttering community.Resources discussed:SheikhBahaei, S., et al.

His research focuses on how the brain controls complex motor behaviors such as speech and breathing, particularly focusing on the role of astrocytes in neural circuits. Growing up with stuttering has influenced his lifelong pursuit to understand the neurobiology of speech and communication. He completed his Ph.D. in Neuroscience through a joint program at University College London and the National Institutes of Health (NIH). He later became one of the first Independent Research Scholars at NIH, where he established his own lab. At Stony Brook University, he continues to investigate the cellular and circuit foundations of speech disorders while also mentoring the next generation of scientists and advocating for more inclusive perspectives on communication.
