My Biography & Research


Sudhakar Vadivelu, DO, joined the Division of Pediatric Neurosurgery at Cincinnati Children's Hospital Medical Center after completing his fellowship in pediatric neurosurgery at Texas Children’s Hospital and neurosurgical residency at Hofstra North Shore- LIJ School of Medicine. While at Hofstra North Shore-LIJ, he acquired additional training in open cerebrovascular surgery and endovascular surgery for specialized training in the care of vascular disorders of the brain and spine. 

Dr. Vadivelu’s interest, specialized training and research background in the role of inflammation in neurogenesis and stem cells, make him uniquely qualified to lead our division in its collaborative efforts with the division of interventional neuroradiology for the treatment of children with vascular disorders of the brain and spine.

In addition, Dr. Vadivelu brings expertise in spinal diseases, brain and spinal cord tumors, neuroendoscopy and neurostimulation.

Clinical Interests

Disorders of the brain and spine; brain and spine tumors; spinal deformity; chiari malformation; hydrocephalus; movement disorders; endovascular/ interventional neuroradiology; neuroendoscopy; neurostimulation

Research Interests

Stem cells; neurogenesis; modulation of cytokine activity
