Chief, Division of Neurosurgery
Global Health

Dr. Barthélemy’s academic interests include teaching and mentoring residents, medical students and graduate students at the SUNY Downstate College of Medicine, as well as at the SUNY Downstate School of Public Health. As a global surgery researcher and neuroscientist, his projects engage the areas of global neurosurgery, translational neurotraumatology and brain repair. He directs the Downstate Global Neurosurgery Laboratory (DGNL) and Co-Directs the Downstate Global Neuroscience Initiative (DGNI).

Global Neurosurgery is defined as the multidisciplinary practice of improving health outcomes and advancing health equity for all people worldwide who are adversely affected by an unmet need for neurosurgical care. Global Neurosurgery practitioners utilize the tools of social medicine and public health to assure safe, timely, affordable and high-quality neurosurgical care for all who need it.

The DGNL is focused on neurosurgical capacity building and advocacy for health equity in neurosurgically underserved communities of Brooklyn, NY, and in several low- and middle-income countries. Current collaborations of the DGNL include work in Haiti, Cuba, Guyana and other Caribbean nations, as well as in Ethiopia and in Pakistan.
