Keith L. Black Chairman and Professor, Department of Neurosurgery Director, Maxine Dunitz Neurosurgical Institute

Keith L. Black, MD serves as Chairman of the Department of Neurosurgery and Director of the Maxine Dunitz Neurosurgical Institute at Cedars-Sinai Medical Center. He also holds the title of Professor in the Department of Neurosurgery. An internationally renowned neurosurgeon and scientist, Dr. Black joined Cedars-Sinai Medical Center in July 1997 and was awarded the Ruth and Lawrence Harvey Chair in Neuroscience in November of that year. Prior to joining Cedars-Sinai, Dr. Black served on the University of California, Los Angeles (UCLA) faculty for 10 years where he was a Professor of Neurosurgery. In 1992 he was awarded the Ruth and Raymond Stotter Chair in the Department of Surgery and was Head of the UCLA Comprehensive Brain Tumor Program.

Dr. Black pioneered research on designing ways to open the blood-brain barrier, enabling chemotherapeutic drugs to be delivered directly into the tumor. His work in this field received the Jacob Javits award from the National Advisory Neurological Disorders and Stroke Council of the National Institutes of Health in June 2000. Dr. Black, along with patients undergoing the first clinical trials of the drug RMP-7, was profiled in 1996 on the PBS program, The New Explorers, in an episode called "Outsmarting the Brain". Dr. Black's other groundbreaking research has focused on developing a vaccine to enhance the body's immune response to brain tumors, use of gene arrays to develop molecular profiles of tumors, the use of optical technology for brain mapping, and the use of focused microwave energy to noninvasively destroy brain tumors. He was featured on the cover of Time magazine in the Fall 1997 special edition "Heroes of Medicine".

Dr. Black serves on the editorial boards of the Neurological Research, Gene Therapy and Molecular Biology, Neurosurgery Quarterly and Frontiers In Bioscience. He was on the National Institutes of Health's Board of Scientific Counselors for Neurological Disorders and Stroke and was appointed to the National Advisory Neurological Disorders and Stroke Council of the National Institutes of Health from 2000 to 2004. He was also selected as a committee member of the California Institute for Regenerative Medicine Independent Citizens Oversight Committee from 2004-2006. He is also a member of numerous professional societies, including the American Association of Neurological Surgeons, Neurosurgical Society of America and the Academy of Neurological Surgery. He also is a Founding Member of the North American Skull Base Society.


 Dr. Black has a unique ability to combine cutting-edge research and an extremely busy surgical practice. Since 1987, he has performed more than 5,000 operations for resection of brain tumors. Dr. Black has had a keen interest in science since childhood. At age 17, he published his first scientific paper, which earned a Westinghouse Science Award. He completed an accelerated college program at the University of Michigan and earned both his undergraduate and medical degrees in six years. He completed his internship in general surgery and residency in neurological surgery at the University of Michigan Medical Center in Ann Arbor. Keith Black was born in Tuskegee, Alabama. Shortly thereafter his family moved to Auburn, Alabama, where his mother Lillian was a schoolteacher, and his father Robert was the principal of Boykin Street Elementary School. Though the Supreme Court had declared school segregation unconstitutional years before Keith Black was born, the state government of Alabama continued to mandate separate schools for black and white children. Robert did his best to circumvent the enforced segregation by employing an integrated faculty in his school, and encouraged his sons to swim in the "whites only" swimming pool. From an early age, Keith Black was fascinated by biology, and taught himself to dissect frogs. Encouraging his son's interest, Robert bought a cow's heart for his son to dissect. When Keith was ten, Robert Black moved his family to Cleveland, Ohio, seeking superior educational opportunities for his two sons. As a teenager, Keith joined an apprentice program at Case Western Reserve University to learn basic laboratory skills. While still in high school, he took a part-time job at Cleveland's St. Luke's Hospital. As an assistant to Frederick Cross and Richard Jones, inventors of the Cross-Jones artificial heart valve, he learned to perform transplant surgeries and heart valve replacements on laboratory dogs. In the course of his work in the Cross-Jones laboratory, he observed damaged red blood cells in patients with heart valve replacements. These observations formed the basis of Black's first scientific paper, published at age 17. The paper also won him the national Westinghouse Science Talent Search competition. After graduating from Shaker Heights High School, he was admitted to the University of Michigan Medical School's accelerated program, allowing him to complete an undergraduate degree and medical school in only six years.

At the beginning of his medical studies, he became fascinated by the workings of the brain. In addition to studying the anatomy of the brain, he pursued studies in chemistry, physiology, psychology, philosophy, religion and mysticism, in an attempt to grasp the mechanism of human consciousness. In the end, this multidisciplinary exploration led him back to an intensified study of the physical structure of the brain. For his medical specialty, he chose to pursue one of the most notoriously difficult areas of medicine, neurosurgery.

A newly minted doctor at age 24, Black remained at the University of Michigan to complete an arduous internship and neurosurgical residency. In 1987, he joined the medical school of the University of California, Los Angeles (UCLA) as an assistant professor of neurosurgery. Of all the challenges facing the neurosurgeon, the most difficult involve the removal of tumors from the brain: cut too much and the brain is permanently damaged; cut too little and the cancer will probably recur. Over the next decade, Keith Black attacked the problem from every possible angle, perfecting his dexterity as a surgeon while exploring breakthroughs in basic science to devise new strategies for combating brain cancer. Chemotherapies that proved successful in treating other cancers were largely ineffective in cases of brain cancer. The brain is protected by a dense mesh of capillaries, the so-called "blood-brain barrier" -- that diverts and dilutes most medications before they can enter the brain. Since medical school, Black had been fascinated by leukotrienes, naturally occurring compounds that enable swelling around traumatic injuries. Among other properties, leukotrienes cause the capillaries to leak. Black conjectured that similar substances, applied to the blood-brain barrier, could permit therapeutic chemicals to enter the brain. Unfortunately, leukotrienes affect the capillaries of healthy brain tissue as well as those of tumors, exposing the brain to the toxic effects of the chemicals. Undaunted, Dr. Black continued his search for a compound that would facilitate effective chemotherapy for brain cancer.

At last, Black identified a naturally occurring peptide called bradykinin. Unlike the leukotrienes, bradykinin only affects the blood vessels of cancerous tissue, allowing therapeutic chemicals to attack brain tumors without affecting the healthy tissue of the brain. In 1994, Dr. Black patented a novel therapy, employing RMP-7, a synthetic version of bradykinin. That same year, Dr. Black was appointed to an endowed professorship at UCLA, and named to head the school's Comprehensive Brain Tumor Program, where he expanded his search for new cancer therapies. After ten years at UCLA, Dr. Black moved to the neighboring Cedars-Sinai Medical Center to lead the newly formed Maxine Dunitz Neurological Institute. While running the Neurological Institute at Cedars-Sinai, Dr. Black also served for five years on the faculty of the University of California Irvine School of Medicine. By this time, his work had drawn national attention. He was profiled on the public television series The New Explorers, the magazine Esquire included him on its list of "The 21 Most Important People of the 21st Century," and TIME magazine featured him on the cover of a 1997 special edition, "Heroes of Medicine." At Cedars-Sinai, Dr. Black's search for new therapies produced a second major discovery. Previous research had revealed that many cancers are effectively blocked by the human immune system, but that certain brain cancers produce a substance that renders them invisible to the body's natural defenses. This substance, known as transforming growth factor-beta (TGF-beta), became the next target of Dr. Black's attention. He devised a novel therapeutic approach in which cancer cells are harvested from the individual patient, cultured, and genetically altered to remove their capacity for producing TGF-beta. Reintroduced into the patient's system, they stimulate the body's natural immune defenses. The immune system responds immediately to the re-engineered cancer cells, and continues attacking whatever cancer cells surgery or other therapies may have missed. Dr. Black has continued his exploration of the body's natural capacity to defend itself against cancer, extracting a patient's white blood cells and training them in the test tube to search out and destroy cancer cells. In laboratory rats, this process successfully eliminated glioblastomas, among the most pernicious brain tumors. Of the handful of surgeons who specialize in brain tumor surgery in the United States, few perform more than 100 surgeries over the course of a year; Keith Black typically performs more than twice that number in a given year. In the first two decades of his career he performed well over 5,000 such operations. In many cases, Dr. Black has saved the lives of patients with brain tumors that other surgeons believed were inoperable. He has pioneered a new surgical approach to clial chordoma, a deadly cancer that occurs at the base of the skull. Previously, surgeons could only reach these tumors by slicing though the brain, causing irreversible damage. Black pioneered a method of reaching the skull base through the nasal passage, extracting the cancerous tissue without touching the brain at all. In 2007, Dr. Black opened a new brain tumor research center at Cedars-Sinai, named for the late Johnnie L. Cochran, Jr. The renowned defense attorney was a former patient of Dr. Black's and a longtime supporter of the center's fundraising efforts. At the Cochran Center, he continues to develop new approaches to the treatment of brain cancer. He has explored new uses of magnetic resonance imaging (MRI) technology, including three-dimensional and real-time imaging processes that enable the surgeon to identify and protect "eloquent" brain tissue -- responsible for thought, movement or speech -- during surgery. He has also made use of precisely targeted microwave radiation to kill cancer cells, a computer-driven technology that may someday be performed remotely, without requiring the physical presence of the surgeon in the operating room. Keith Black makes his home in Los Angeles, with his wife, Carol, who is also a distinguished physician. They have two children. Away from the laboratory and the operating room, Dr. Black shows a pronounced taste for outdoor adventure. He enjoys mountain climbing, whitewater rafting and skydiving. He has trekked through the Himalayas, rafted Africa's Zambezi River and climbed Mt. Kilimanjaro. His autobiography, Brain Surgeon, was published in 2009. Johnnie L.
