Research

Ralph Weissleder serves as the Director of the Center for Systems Biology at MGH. He is a Professor at Harvard Medical School, Director of the Center for Molecular Imaging Research, and Attending Clinician (Interventional Radiology) at MGH. Dr. Weissleder is also a member of the Dana Farber Harvard Cancer Center, an Associate Member of the Broad Institute (Chemical Biology Program) and a member of the Harvard Stem Cell Institute (HSCI). He is a world leader in applying molecular imaging tools to the study of complex human diseases. He has made fundamental discoveries in early disease detection, development of nanomaterials for sensing and systems analysis. His research has been translational and several of his developments have led to advanced clinical trials.

Dr. Weissleder is currently the principal investigator of several RO1 NIH grants, a P50 Center grant, a U24 grant, and a UO1 consortium focusing on nanotechnology. He has published over 500 publications in peer reviewed journals. His work has been honored with numerous awards including the J. Taylor International Prize in Medicine, the Millenium Pharmaceuticals Innovator Award, the AUR Memorial Award, the ARRS President's Award, The Society for Molecular Imaging Lifetime Achievement Award and the Academy of Molecular Imaging 2006 Distinguished Basic Scientist Award.
