Peleg Horowitz is a neurosurgeon with expertise in brain and skull base tumors as well as endoscopic and open surgical approaches to the skull base. This includes incorporation of advanced stereotactic and 3-D surgical planning for operative treatment and radiosurgery of both benign and malignant brain and skull base tumors, including gliomas, meningiomas, schwannomas, and pituitary tumors. Along with Endocrinologist Susan Sam, MD, he leads the neurosurgical efforts of the University of Chicago Pituitary and Neuroendocrine Disorders program.

In addition to his interest in neurosurgical oncology, he also practices general neurosurgery, treating patients with a wide range of diseases, including head trauma in adults and children, and served as the Interim Director of Neurosurgical Trauma for the opening of the University of Chicago Level One Trauma Center.

His past scholarly work has focused on the pathogenesis and management of nervous system tumors, and his research has identified several novel genes that drive the formation of meningiomas and pediatric gliomas. His research on tumor genetics has been published in Nature Genetics and Proceedings of the National Academy of Sciences of the United States of America, and has been funded by the Brain Science Foundation and the US Department of Defense Neurofibromatosis Research Program.

Horowitz received his bachelor’s degree in biology and a PhD in neuroscience from Northwestern University, as well as an MD from the Feinberg School of Medicine at Northwestern University. He completed his internship and residency at Brigham and Women’s Hospital/Children’s Hospital Boston, and a skull base surgical neurooncology fellowship at the University of Texas MD Anderson Cancer Center.
