Nir Lipsman
Nir Lipsman

The Division of Neurosurgery at Sunnybrook Health Sciences Centre welcomes Nir Lipsman as a new surgeonscientist on faculty.

Nir grew up in the greater Toronto area, and completed his medical training at Queen’s University in Kingston, Ontario and then entered the neurosurgery residency program at University of Toronto. While in residency, he completed his Ph.D. through IMS under the supervision and mentorship of Dr. Andres Lozano, focused on early phase clinical trials of deep brain stimulation and MR-guided focused ultrasound. Following residency, Nir completed a fellowship in Stereotactic & Functional Neurosurgery at University Health Network.

Nir’s primary research interests are investigating the brain circuits driving neurologic and psychiatric disorders. He helped develop the first human trials of deep brain stimulation in anorexia nervosa, bipolar disorder, and schizophrenia, and the first human experience of focused ultrasound in essential tremor, Parkinson’s disease and Alzheimer’s. He has received the K.G. McKenzie Prize from the Canadian Federation of Neurological Sciences as well as the Shafie S. Fazel Outstanding Resident Surgeon and Investigator Award from the U of T Department of Surgery. Nir’s work has been funded by several peer-reviewed grants, including CIHR and the Focused Ultrasound Foundation, and he has published over 70 papers and textbook chapters.

Nir was recruited to Sunnybrook to help build the functional neurosurgery program, and where he hopes to further develop novel clinical applications for focused ultrasound. Appreciating the wide scope of his activity, he has cross -appointments to both the Division of Neurology (Department of Medicine) and the Department of Psychiatry. The Division of Neurosurgery at Sunnybrook Health Science Centre is proud to have attracted Dr. Lipsman as a recruit and is looking forward working with him.

Outside of work, Nir loves nothing more than to spend time with his wife, Sarit, a visual artist, and their two children, Leah and Elie.
