Dr. Pashtun Shahim’s research interests include neurodegenerative and traumatic brain injury research.
MD, University of Gothenburg
PhD, University of Gothenburg
Dr. Shahim received his medical degree from the University of Gothenburg, Sweden, in 2011, and a PhD in neuroscience from the University of Gothenburg in 2015. He completed a postdoctoral fellowship in traumatic brain injury at the Department of Neurology at Washington University in St. Louis. He also has experience working as physician in the Department of Neurochemistry at Sahlgrenska University Hospital in Sweden.
In his current role as a physician-scientist in the Rehabilitation Medicine Department, Dr. Shahim evaluates and treats patients with neurologic conditions, in particular those with traumatic brain injury and he co-directs a multidisciplinary traumatic brain injury team.
Dr. Shahim’s main research interests include discovery, development, and validation of fluid and advanced imaging biomarkers for detection and prognosis of traumatic brain injury and resulting neurodegeneration.
Dr. Shahim has published over 50 peer-reviewed articles, editorials, and a book chapter.
