Dr. Rosen is a world-leading expert in functional neuroimaging. Over the past thirty years he has pioneered the development and application of many novel physiological and functional nuclear magnetic resonance techniques to measure hemodynamic and metabolic changes associated with brain activation and cerebrovascular insult as well as complementary tools to measure microvascular and microstructural morphology. These and other techniques he has developed are used by research centers and hospitals throughout the world to study and evaluate patients with stroke, brain tumors, dementia, and neurologic and psychological disorders. Most recently, Dr. Rosens work has focused on the integration of fMRI data with information from other modalities, including positron emission tomography (PET), magnetoencephalography (MEG) and noninvasive optical imaging. By using fMRI tools to evaluate the linkage between neuronal and physiological (metabolic and hemodynamic) events during periods of increased neuronal activity, his studies will allow researchers to better interpret fMRI signal changes and develop new ways to probe brain function.

Dr. Rosen leads the activities of several large interdisciplinary and inter-institutional research programs including the NIH Blueprint-funded Human Connectome Project, the NIBIB Regional Resource Center, the Center for Functional Neuroimaging Technologies (CFNT), and the Biomedical Informatics Research Network (BIRN) Collaborative Tools Support Network. He is Principal Investigator/Program Director for two neuroimaging training programs. He has authored more than 300 peer-reviewed articles as well as over 50 book chapters, editorials and reviews.
