Research/Clinical Interest

Dr. Johnson’s research uses advanced magnetic resonance images of the animal brain in order to study the structure and connectivity of the white matter in the equine brain as well as to identify MRI biomarkers for canine degenerative myelopathy and to improve our ability to understand and diagnose canine epilepsy.
