Assistant Professor of Neurological Surgery, Columbia University Medical Center
Director, Translational Brain Tumor Lab

Dr. Sonabend is a cancer researcher and the principal investigator of the Translational Brain Tumor Lab at Herbert Irving Comprehensive Cancer Center at Columbia University. Dr. Sonabend’s research focuses on epigenetic regulation of transcription in gliomas, the use of molecular markers to personalize treatments for patients with malignant brain tumors, and the delivery of these treatments directly into the brain to improve their efficacy while avoiding unnecessary side effects.  In addition to leading this lab, Dr. Sonabend is a brain tumor surgeon and he is involved in several clinical trials to test novel and promising therapies for patients with brain tumors.

Edgar Ferran Buendia GonzalezEdgar Gonzalez
Postdoctoral Research Scientist

Edgar is a Postdoctoral Research Scientist at the Translational Brain Tumor Lab. He is interested in understanding the contribution of chromatin structure on gene expression, and its implications to development and cancer. His previous work includes the study of chromatin architecture by investigating how the formation and maintenance of chromatin domains contribute to developmentally regulated gene expression. Edgar has also experience studying epigenetic regulation of tumor suppressor genes in human cancer.
