Our research focuses on understanding the neural circuits and cellular mechanisms underlying voluntary motor control, particularly the role of glial cells—such as astrocytes—in modulating neuronal activity. We explore how astrocytes interact with neurons to regulate complex motor behaviors, with a special focus on circuits involved in speech production and respiratory control. By utilizing genetic, optical, and electrophysiological techniques, our research aims to dissect the contributions of specific cell types to motor circuit function. A significant aspect of our work addresses the neural basis of speech and its disorders, including developmental stuttering. By studying how astrocytes influence respiratory behaviors, we aim to uncover the mechanisms connecting breathing and speech, translating discoveries from bench to bedside and back.
