        Dr. Cage has comprehensive neurosurgical training in traumatic brain injury, traumatic spine injury, degenerative and oncologic spine disorders, as well as extra-axial and intra-axial brain tumors.

        Her research interest is in working towards eliminating health disparities in neurosurgical outcomes. She specifically focuses on understanding the association between socioeconomic and demographic characteristics and patient outcomes following traumatic brain injury.

        Dr. Cage has authored over 30 research articles and has received grants to support her research including the UCSF Genentech Foundation Research Fellow Award and the Howard Hughes Medical Institute Research Fellow Award. Her research has been recognized with the Lucien J. Rubenstein Memorial Award from the American Brain Tumor Association, the Young Investigator Award from the Pediatric Brain Tumor Foundation, and the Best Basic Science Research Paper Award from UCSF Neurological Surgery residency program.

        She is dedicated to student and resident mentorship and training. Dr. Cage grew up in the San Jose area and is honored to be able to work at SCVMC and serve the community where she was raised.​

        Jayant Menon, MD



        Medical Doctor

        Dr. Jayant Menon completed his neurosurgery residency at the University of California, San Diego. He advanced his training in design of advanced biomedical instrumentation with a Master’s degree in Biomedical engineering. Dr. Menon completed subspecialty surgical training at Stanford University in Functional Neuromodulation.

          Dr. Menon’s Neuromodulation practice for pain includes Transforaminal Epidural Steroid Injections, Medial nerve blocks, Spinal Cord Stimulation, and Intrathecal Pain Pumps. Neuromodulation can be a successful way to treat pain that lingers after spine surgery, pain from peripheral vascular disease, and pain from peripheral neuropathy. Dr. Menon provides Deep Brain Stimulation for patients with Parkinson’s disease as well as Vagal Nerve Stimulation for patients with seizure disorders.

          As a key part of his role at Valley Medical Center, Dr. Menon provides surgical and critical care treatment for patients that experience traumatic brain and spine injury. His research interests are in the design and development of tools to help patients restore function and achieve a high quality of life. ​​

          VIVEK P. BUCH, MD

          Medical Doctor

          Dr. Buch is a Clinical Instructor at Stanford University in Epilepsy and Stereotactic surgery. Dr. Buch completed his undergraduate and medical training with honors in the direct BA/MD program at Brown University. During medical school he was selected as a HHMI-NIH Research Scholar for which he spent one year living on the NIH campus studying graph theoretic network analysis and connectomics. He then completed his neurosurgical residency at the University of Pennsylvania.

            Dr. Buch is a neural engineer, computational scientist, entrepreneur, and innovator. His clinical interests are in the treatment of epilepsy, eloquent region mapping for tumor or epilepsy resections, MR-guided focused ultrasound, restorative and robotic/stereotactic surgery, and general neurosurgery. His clinical interest in developing innovative minimally invasive surgical approaches has led him to develop new patent pending camera-based technology for automated surgical guidance. Academically his research focuses on designing human-machine interfaces to create novel treatments, devices, and systems to drive the next generation of healthcare.​

            Ahmed Mohyeldin, MD, PhD



            Medical Doctor

            Dr. Mohyeldin completed his undergraduate education at Emory University with a degree in neuroscience and behavioral biology. Having been selected as an All-American Athlete, he was drafted to play professional soccer in Atlanta prior to medical school.

              Dr. Mohyeldin completed his undergraduate education at Emory University with a degree in neuroscience and behavioral biology. Having been selected as an All-American Athlete, he was drafted to play professional soccer in Atlanta prior to medical school.

              Dr. Mohyeldin completed his medical education at George Washington University. During medical school he was awarded a grant from the American Association of Neurological Surgeons and from the Maryland Stem Cell Research Fund to pursue a post-doctoral research fellowship at Johns Hopkins University under the mentorship of Dr. Alfredo Quinones-Hinojosa.

              His research investigated developmental transcriptional programs coopted by brain cancer with a specific focus on chordomas and glioblastomas. During this time, he developed the first animal model for chordoma and identified the transcription factor brachyury as a novel therapeutic target, which is currently the focus of a major NIH clinical trial as well as multiple drug design studies for chordoma patients.

              Dr. Mohyeldin pursued his neurosurgical training at Ohio State University, during that time he was awarded the R25 grant from NIH to further pursue this work. After completing his residency, he remained at OSU and pursued a clinical fellowship with Dr. Daniel Prevedello and Ricardo Carrau in advanced skull base and endoscopic cranial surgery.

              He comes to the Neurosurgery Department to work with Dr. Juan Fernandez-Miranda and collaborate with leading basic scientists at Stanford to identify and target important transcriptional programs that maintain cancer stem cell populations in chordoma to find a meaningful cure for this disease.​
