About Our Neurosurgery Research

Neurosurgery faculty conduct a diverse range of basic and clinical research aimed at better understanding neurologic conditions and discovering, developing, and improving treatments for patients, as well as evaluating patient outcomes. The goal is to advance knowledge to improve care for patients worldwide.

Neurosurgery faculty publish their research findings in leading academic journals and books, and are invited to present their work at conferences nationally and internationally.

Below are the main research interests of our faculty. For faculty with individual reports describing their current research in detail, click on their names. To visit our faculty members’ Harvard Catalyst profiles, which include recent selected publications, click on the Catalyst link.
