Radiology Conference Room N2E14C

Robert D. Zimmerman, MD, is director of diagnostic imaging and a professor of radiology at the New York–Presbyterian Hospital/Weill Cornell Medical College (New York, NY). He received his medical degree from Albert Einstein College of Medicine (New York, NY). After internship and radiology residency at Montefiore Hospital and Medical Center (New York, NY), he completed a fellowship in neuroradiology at George Washington University Medical Center (Washington, DC).

His multimodality neuroimaging research and clinical interests include disffusion imaging, diffusion tensor imaging, and perfusion imaging, particularly in the emergent setting. Dr. Zimmerman chairs the neuroradiology examination section of the American Board of Radiology. He is a past president of the Eastern Neuroradiology Society and the New York Roentgen Society and is currently president-elect of the American Society of Neuroradiology.
