Melanie Hayden Gephart
Professor of Neurosurgery and, by courtesy, of Neurology
BioI am a brain tumor neurosurgeon, treating patients with primary and metastatic brain tumors. I treat patients with malignant and benign tumors, including glioma, brain metastases, meningioma, and vestibular schwannomas. I direct the Stanford Brain Tumor Center and the Stanford Brain Metastasis Consortium, collaborative unions of physicians and scientists looking to improve our understanding and treatment of brain tumors. My laboratory seeks greater understanding of the mechanisms driving tumorigenesis and disease progression in malignant brain tumors. We study how rare cancer cell populations survive and migrate in the brain, inadvertently supported by native brain cells. We develop novel cell free nucleic acid biomarkers to track brain cancer treatment response, relapse, and neurotoxicity. Our bedside-to-bench-to-bedside research model builds on a foundation of generously donated patient samples, where we test mechanisms of brain cancer growth, develop novel pre-clinical models that reliably recapitulate the human disease, and facilitate clinical trials of new treatments for patients with brain cancer.
Florette K. Gray Hazard
Associate Professor of Pathology and of Pediatrics
Current Research and Scholarly InterestsMy scholarly pursuits are primarily focused on the study of death and disease in the pediatric population. It is through this work that I am able to explore fundamental concepts of neoplasia, such as histogenesis and mutagenesis, while utilizing a variety of investigational techniques.

Stefan Heller, PhD
Edward C. and Amy H. Sewall Professor in the School of Medicine and Professor of Otolaryngology - Head & Neck Surgery (OHNS)
Current Research and Scholarly InterestsOur research focuses on the inner ear, from its earliest manifestation as one of the cranial placodes until it has developed into a mature and functioning organ. We are interested in how the sensory epithelia of the inner ear that harbor the sensory hair cells develop, how the cells mature, and how these epithelia respond to toxic insults. The overarching goal of this research is to find ways to regenerate lost sensory hair cells in mammals.
