RESEARCH SUMMARY
As the former Neuro-Oncology Branch (NOB) chief from 2014 to 2024, Dr. Gilbert developed a unified team to perform cutting-edge research that advances knowledge in the brain tumor field. These findings were used to develop robust clinical trials, which improved patient outcomes through innovative combination treatments and precision medicine approaches.
Today, Dr. Gilbert is a scientist emeritus. In his previous role as chief and senior investigator, he led the NOB's Translational Immunology Research Program and Precision Medicine Research Program. His primary research concentrations were in the areas of immunotherapy and precision therapy. For immunotherapy, he and his team worked to develop combination therapies that increase immune cell recruitment to the tumor site and improve patient selection in clinical trials to maximize benefit for those enrolled. His Precision Medicine Research Program focused on utilizing basic and computational biology to develop synthetic lethal drug pairs that can overcome the challenges of driver mutation targeting—offering a wider percentage of patients effective therapeutic options.

Areas of Expertise
Research
Advances in therapeutic approaches for patients with primary brain tumors have struggled to keep pace over the last few decades, as surgery, radiation, and chemotherapy remain the staples of clinical care. In his previous role as a senior investigator at the Neuro-Oncology Branch (NOB), Dr. Gilbert established a robust Translational Immunology Research Program with a multidisciplinary research group to improve treatment and patient outcomes. Dr. Gilbert’s vision was to not only find effective treatments for brain tumors, but to also establish paradigms of clinical and translational investigation that can then be utilized worldwide to help other physicians make a collective impact in neuro-oncology.
Because heterogeneity is a hallmark of brain tumors, Dr. Gilbert’s focus was exploring precision medicine and immunotherapy options by utilizing computational, biological, and clinical trial approaches stemming from a strong basic research program. His roles in founding and establishing the Brain Tumor Trials Collaborative (BTTC) and the Collaborative Ependymoma Research Network (CERN) were crucial foundational pillars to establish a hypothesis-driven research program that supported pre-clinical and clinical studies to advance therapies for rare cancers. The BTTC and CERN are now part of large, multi-institutional networks that focus on delivering clinical trial options for malignant gliomas around the country, supported by molecular profiling, patient outcomes studies, and innovative drug discovery, among other goals.

Biography
Mark R. Gilbert, M.D.
Dr. Gilbert retired as chief of the Neuro-Oncology Branch (NOB) in May 2024 and is now an NIH scientist emeritus.
He received his Doctor of Medicine degree from Johns Hopkins University in 1982 (Alpha Omega Alpha). He remained at Johns Hopkins to complete residencies in internal medicine (1982-1985), neurology (1984-1988), and neuro-oncology fellowship training with the Keck Foundation Fellowship (1986-1987).
He subsequently held academic research positions at Johns Hopkins University’s Department of Neurology and Oncology Center, the University of Pittsburgh Cancer Institute’s Department of Neurology, and Emory University’s Department of Neurosurgery. He then had a 14-year tenure at the Department of Neuro-Oncology at The University of Texas’s MD Anderson Cancer Center before becoming chief of the NOB in 2014.
Over the course of his career, Dr. Gilbert has been an integral part of various national and international clinical trial initiatives. Beginning in 2005, he was appointed director of the Brain Tumor Trials Collaborative (BTTC), a multi-center clinical trials consortium that is a large part of the NOB’s ongoing efforts to deliver accessible clinical trial options to patients across the country. Additionally, Dr. Gilbert is the founder, former director, and principal investigator of the Collaborative Ependymoma Research Network (CERN), a consortium formed in 2006 to study ependymoma—a rare central nervous system cancer. CERN supports basic research, clinical trials, patient outcomes research, and educational efforts in North America and Europe.
Notably, Dr. Gilbert received the Blanche Bender Endowed Professorship in Cancer Research in 2009 from the MD Anderson Cancer Center, and the National Institutes of Health Director’s Award in 2016 for his impactful contributions to the field.
