Dr. George Ibrahim is a paediatric neurosurgeon at The Hospital for Sick Children (SickKids) and an Assistant Professor in Biomedical Engineering, the Institute of Medical Sciences, and the Department of Surgery at the University of Toronto. He is also a Scientist in the Neurosciences and Mental Health program at the SickKids Research Institute.

Dr. Ibrahim’s clinical and research interests include the surgical treatment of medically intractable epilepsy, spasticity and functional disorders in children. 

He plays an active role in the comprehensive epilepsy, dorsal rhizotomy, and deep brain stimulation programs at SickKids. His research lab is dedicated to the study of neural networks in children with epilepsy and functional disorders through a combination of connectomiccomputational neuroscience, and machine learning approaches. His work has yielded insights into personalized treatments for children targeting specific network impairments, and the development of novel devices and treatment strategies. His interests also include the intersection of global health, neuroethics, and neurosurgery, including the provision of neurosurgical care to the world's most vulnerable children.

“We tried everything”: Team of Toronto surgeons doesn’t give up on young girl with persistent seizures

Neurosurgeons from SickKids and Toronto Western Hospital (TWH) have performed the first deep brain stimulation (DBS) to treat drug-resistant paediatric epilepsy in Canada. With only 40 published cases of the procedure being performed in children for this condition, Andi Dreher, 9, is among the first in the world to undergo this treatment.

Division of Neurosurgery

We're the largest and longest running Neurosurgery Division in Canada, and one of the best in the world.
