Michael Hylin, Associate Professor and Program Director

Brain and Cognitive Sciences

Dr. Michael Hylin received his Ph.D. in Neuroscience and Behavior from Northern Illinois University in 2010. After which he was a postdoctoral fellow in the laboratory of Dr. Pramod Dash at the University of Texas Medical School in Houston. Dr. Hylin’s research focuses on the biochemical systems that underlie neurocognitive dysfunction following traumatic brain injury (specifically mild and repetitive injury). This includes pathways associated with the extracellular matrix, inflammation and axonal injury. The goal of his research is to determine how manipulation of dysfunctional pathways can lead to behavioral recovery. Part of this strategy involves researching the mechanisms involved in memory recall in order to develop novel strategies for neurocognitive rehabilitation following traumatic brain injury. Another strategy is combining environmental enrichment and cognitive rehabilitation with pharmacological treatments in order to induce functional recovery.
