Vicky Johnson: brain researcher who studied the links between traumatic brain injury and neurodegenerative disease

Until her untimely death aged 44, Scottish born Vicky Johnson, associate professor of neurosurgery at Perelman School of Medicine, University of Pennsylvania, led landmark international research exploring the biology and pathology of traumatic brain injury (TBI), with projects spanning complex pre-clinical models to human pathology studies. She established herself as one of the leaders in TBI research, directing multiple programmes and mentoring many students and postdoctoral researchers.
