Stieg was born in Milwaukee, WI, the third son of Betty and Edwin Stieg. He attended parochial schools for his primary and secondary education, and then enrolled at the University of Wisconsin–Madison in 1970.
Stieg earned a B.S. degree in zoology from the University of Wisconsin–Madison in 1974. He pursued graduate studies in neuroanatomy and neuroscience at Albany Medical College/Union University, and was awarded a Ph.D. in 1980. He then attended medical school at the Medical College of Wisconsin in Milwaukee, completing his M.D. degree in 1983.
Stieg was a resident in general surgery and neurosurgery at the University of Texas-Southwestern Medical School and Parkland Memorial Hospital. Thereafter, he did a fellowship in cell transplantation for restorative neurological function at the Karolinska Institute in Stockholm, Sweden.
Stieg joined the faculty of Harvard Medical School, Brigham and Women's Hospital, and Children's Hospital of Boston in Boston, Massachusetts in 1989. He developed research and clinical interests in cerebral protection and restorative function, neural transplantation, neuronal regeneration after stroke, cerebrovascular surgery, and surgery of the skull base. His research has focused on the mechanisms of injury in the central nervous system after trauma and the mechanisms of cell-membrane transport and their implications after traumatic brain injury.
In 2000, Stieg was named Professor and Chair of the Department of Neurosurgery at Weill-Cornell Medical College and New York-Presbyterian Medical Center in New York City. He has been listed in Who's Who in Health and Medical Services and The Best Doctors in America. He has authored more than 100 peer-reviewed publications in the medical literature and has co-edited a textbook titled Intracranial Arteriovenous Malformations. In 2015, Stieg was named President of the Brain Tumor Foundation
