ASNR Awards Daniel Reich, MD, PhD, with the 2025 Outstanding Contributions in Research Award
Dr. Daniel Reich, Senior Investigator at NIH/NINDS, leads clinical studies on multiple sclerosis and is an attending neuroradiologist at the NIH Clinical Center. He is also Adjunct Professor of Radiology, Neurology, and Biostatistics at Johns Hopkins and of Neurology at Yale. He earned his undergraduate degree in math and physics from Yale, a PhD in neurophysiology from The Rockefeller University, and an MD from Cornell.
Dr. Reich founded the North American Imaging in Multiple Sclerosis (NAIMS) Cooperative and serves as federal liaison to several multiple sclerosis-related boards and committees. He is a Fellow of the American Association for the Advancement of Science and an elected member of the Association of American Physicians and the American Society of Clinical Investigation, and he has received prestigious awards for his research, including the National Multiple Sclerosis Society’s Barancik Award for Innovation in Multiple Sclerosis Research and the NIH Graduate Partnership Programs Outstanding Mentor Award.
His NIH lab focuses on advanced MRI techniques for multiple sclerosis, conducting interventional clinical trials and exploring noninvasive imaging modalities to understand tissue damage mechanisms. In 2017, Dr. Reich’s lab discovered that human and nonhuman primates have a lymphatic system in the membranes covering the brain and showed how that system can be imaged noninvasively with MRI.
Dr. Reich has published over 300 papers, given more than 150 invited lectures globally, and supervised numerous scientists and clinicians in training.
