Natalia S. Rost, MD, MPH

Natalia S. Rost, MD, MPH is Stroke Division Chief in the Department of Neurology at Massachusetts General Hospital and Professor of Neurology at Harvard Medical School. A cum laude graduate of Boston University School of Medicine, she holds a Master’s degree from Harvard School of Public Health and is trained in Neurology and Vascular Neurology at Partners (Massachusetts General Hospital/Brigham and Women’s Hospital) residency and fellowship programs.

Rost is a clinician-scientist and international expert on neuroimaging markers of cerebrovascular disease, stroke genetics, and big data science for outcome prediction in patients with acute stroke. Her line of research on the role of white matter disease burden and mechanisms of brain resilience in stroke has been continuously funded since 2007, and Rost is currently the Samana Cay MGH Research Scholar and Principal Investigator of two NIH R01 awards and of DISCOVERY, a collaborative national network supported by one of the largest single-study awards to the MGH Neurology department, a U19 jointly funded by the NINDS/NIA to address post-stroke cognitive impairment and dementia in the United States.

Rost is an author of numerous peer-reviewed publications, book chapters, a co-author of the MGH Handbook of Neurology, and medical editor of the Harvard Medical School Special Health Report on stroke. She is an accomplished mentor, clinical educator, and recipient of the 2017 MGH Neurology Department’s Ray Adams Clinical Mentor Award and of the 2012 Michael S. Pessin Stroke Leadership Award from the American Academy of Neurology. She serves as Assistant Editor of the journal Stroke and Chair of the Science Committee of the American Academy.
