Research Summary

Locomotion is a deceptively simple, yet essential behavior. We are interested in how neural circuits in the brainstem and spinal cord develop and ultimately control the speed and direction of locomotor movements. To do this, we study innate and learned exploratory and evasive behaviors in developing zebrafish using a combination of behavioral, imaging, electrophysiological and molecular approaches. By revealing basic principles of motor circuit organization, we hope to provide insights into disorders that affect our capacity to move, like Parkinson's disease, epilepsy or spinal injury.
