Dr. Stevens’ research centers on quantitative approaches to injury and repair within the central nervous system.
His group seeks to generate a comprehensive anatomical and functional map of neural injury and repair following insults such as trauma, stroke, anoxia and sepsis. Several projects have evaluated the relationship between critical illness and central or peripheral nervous system dysfunction. Ongoing projects deploy quantitative brain mapping to probe recovery of consciousness and cognitive function in patients who have experienced acute neurologic insults from trauma, stroke, cardiac arrest and sepsis.
Dr. Stevens is the principal investigator in a study funded by the Brain Science Institute to track recovery after severe traumatic brain injury using multiparametric MRI and tablet-based neuropsychological assessments. He leads the Neuroimaging for Coma Emergence and Recovery (NICER) project, a multi-site, prospective observational cohort study of patients with severe traumatic brain injury who are serially evaluated with MRI and detailed cognitive phenotype analysis. The overarching goal is to generate transformative interventions for neurological recovery.
