Aaron A. Cohen-Gadol (Persian: هارون کهن-گادل, born November 23, 1970) is a professor of neurological surgery in the department of neurosurgery at Indiana University School of Medicine and a neurosurgeon at Indiana University Health specializing in surgical treatment of brain tumors and aneurysms.[1][2] He performs removal of complex brain tumors via endoscopic techniques, which use the nasal pathways instead of opening the skull.[3][4]

Cohen founded the Neurosurgical Atlas,[5] a non-for-profit organization, aimed at advancing the care of patients with neurosurgical disorders via introduction of novel and efficient surgical techniques into practice.[6]


Cohen completed his undergraduate (B.A. in bioengineering) and M.D. degrees from the University of California at San Diego and Keck School of Medicine of USC, respectively.[7] Cohen completed his residency training in neurosurgery at Mayo Clinic in Rochester, Minnesota. He also completed advanced fellowship training in two subspecialties: epilepsy surgery (Yale University) and skull base/cerebrovascular surgery (University of Arkansas Medical Sciences.) He also attained a master's degree in Clinical Research from Mayo Clinic Graduate School.[8]


Cohen performs brain surgery for a variety of brain tumors (gliomas and meningiomas,) complex brain tumors (skull base, acoustic, and pituitary tumors,) cerebral aneurysms and arteriovenous malformations, trigeminal neuralgia, hemifacial spasm, and seizures.[9] He developed endoscopic techniques that allow a surgeon to remove a brain tumor without opening the patient's skull, via the nasal passage.[4] He also has helped refine fluorescent technologies that cause a brain tumor to "glow," making it easier for a surgeon to see precisely where its margins are.[9] In cooperation with the Brain Aneurysm Foundation, he created the Brain Aneurysm mobile application.[10]

Cohen is also involved in guiding and teaching fellow neurosurgeons in handling complex surgical procedures including brain tumors, aneurysms and arteriovenous malformations.[11] As of 2018, he is the Director of Neurosurgical Oncology/Brain Tumor Surgery at the Indiana University Department of Neurosurgery.[12] Cohen is the co-founder and co-director of the Center for the Cure of Glioblastoma, part of the Indiana University School of Medicine, which facilitates new treatment options for brain tumor patients by mentoring neuroscientists and researchers.[13]

Cohen serves as the associate editor-in-chief of Neurosurgical Focus, a journal in the field of neurosurgery. He has served on the Board of Directors of the American Association of Neurosurgeons (AANS) and the "Senior" Society of Neurological Surgeons (SNS).[14][15] He has written and contributed to approximately 438 peer-reviewed publications.[16][17]

The Neurosurgical Atlas[edit]

Cohen is the creator and current chief editor of the Neurosurgical Atlas, a non-for-profit organization.[6]

He founded the AANS Operative Grand Rounds in 2009, a web-based resource for training neurosurgeons.[18] The AANS Grand Rounds apps contain a collection of videos that were produced jointly by Cohen, the Neurosurgical Atlas, and the American Association of Neurological Surgeons (AANS).[19][20]

Awards and honors[edit]

Cohen was voted the Health Care Hero of the Year in the State of Indiana in 2009[21][22] for advancements in health care. He was granted the Hemispherectomy Foundation's Humanitarian award and is co-chair of the foundation's Medical Advisory Board.[23]

Personal life[edit]

He volunteers to perform therapeutic surgery on dogs with brain tumors.[9]
