Dr. Gelareh Zadeh, MD, PhD, is Professor and Chair of the Department of Neurologic Surgery at Mayo Clinic in Rochester, Minnesota. She is the David C. and Flora C. Pratt Distinguished Chief Medical Officer for Mayo Clinic Platform and holds the William J. and Charles H. Mayo Professorship.
Dr. Zadeh is a neurosurgeon-scientist specializing in neuro-oncology, with a particular focus on gliomas and meningiomas. Her research investigates the molecular, genomic, and epigenomic characteristics of brain tumors to better understand tumor behavior, predict treatment response, and advance precision medicine.
Her work spans molecular profiling, liquid biopsy, imaging biomarkers, and the tumor microenvironment, with an emphasis on translating scientific discoveries into clinical practice. She leads international research collaborations and clinical trials aimed at improving the diagnosis, treatment, and monitoring of brain tumors.
Dr. Zadeh’s contributions to cancer research have been recognized through numerous awards, including the 2023 Canada Gairdner Momentum Award and the 2021 Farber-Abhijit Guha Award.
