Isaac Kurtzer

---

Isaac Kurtzer studies how the nervous system enables coordinated actions, in particular actions with our upper limb. His research has spanned proprioception, postural anticipation, motor learning, stretch reflexes, and cortical processing. He is currently focused on the process of target re-selection during movement like how we can reliably navigate through a crowded and bustling train station. He trains undergraduate and graduate students on experimental design and data collection and analysis, in addition to teaching a biostatistics course, lectures on the nervous system, and directing the neuroanatomy lab. He is an active member of the movement science community through his own work, reviewing, and research collaborations.

Kurtzer received his Ph.D. in Neuroscience at the Brandeis University, master’s degree in Cognition and Neuroscience at University of Texas at Dallas, and a bachelor’s degree in Psychology at Stephen F. Austin State University.
