Ziya L. Gokaslan, MD, FACS, has been appointed chief of neurosurgery at Rhode Island Hospital and The Miriam Hospital, and chairman of the department of neurosurgery at The Warren Alpert Medical School of Brown University, effective July 1, 2015.Most recently, Gokaslan has served as the vice chairman of the department of neurosurgery, director of the neurosurgical spine program, director of the neurosurgical spine metastasis center and a professor of neurosurgery, oncology and orthopedic surgery at the Johns Hopkins University School of Medicine in Baltimore, Maryland. Prior to joining Johns Hopkins, Gokaslan was an associate professor of neurosurgery at the University of Texas MD Anderson Cancer Center in Houston and served as deputy chair of its department of neurosurgery. Gokaslan’s clinical practice focuses on the radical surgical treatment of both primary and metastatic spinal tumors, sacral neoplasms and spinal cord tumors. He developed many novel approaches for resection of pancoast tumors, spinal neoplasms, as well as sacral tumors, including total sacrectomy and complex spinal and pelvic reconstruction. Gokaslan transformed the surgical treatment of spinal neoplasms and devised techniques rendering certain tumors resectable once deemed inoperable. These led to significant improvement of survival in patients with various neoplastic conditions. His basic research focuses on the development of new animal models to study the pathophysiology of neoplastic spinal cord compression and to define the roles of proteolytic enzymes in tumor invasion and to devise novel therapeutic approaches to treat spinal tumors.
