Dr. Edwardson is a vascular neurologist whose research explores the biological mechanisms behind recovery after brain injury in humans. His interests include the mechanisms of neural repair induced by the brain injury itself as well as those brought about through neurorehabilitation strategies. He primarily studies patients with stroke and focuses on the early phase after injury, a time that may represent a "critical period" during which the brain is better able to learn new skills. He uses multi-omic evaluation of blood samples, including metabolomics, to identify molecular changes that signal neural injury and repair in the brain. Dr. Edwardson also studies recovery using neuro-imaging techniques such as MRI and DTI.
