Lab: Weissleder, Ralph


Dr. Weissleder is the Thrall Professor of Radiology and Professor of Systems Biology at Harvard Medical School, Director of the Center for Systems Biology at Massachusetts General Hospital (MGH), and Attending Clinician (Interventional Radiology) at MGH. Dr. Weissleder is also a member of the Department of Systems Biology at HMS and the Harvard Cancer Center. Dr. Weissleder’s research interests include the development of novel high resolution molecular imaging systems, tools for early disease detection, new and more advanced nanomaterials for imaging, and modeling methods for systems analysis. Increasingly, his work has been focused on reconciling the gap that exists between traditional cell biology and human biology. His work on imaging, nanomaterials and miniaturized sensing technologies has led to a number of new technologies and advanced clinical trials. He is a cofounder of T2Biosystems and Lumicell. Dr. Weissleder is currently the principal investigator of several National Institute of Health grants and consortia. He has published over 800 publications in peer reviewed journals and has authored several textbooks. He has received the J. Taylor International Prize in Medicine, the Millennium Pharmaceuticals Innovator Award, the Society for Molecular Imaging Lifetime Achievement Award and is a member of the German National Academy of Sciences (Leopoldina) and of the US National Academies of Medicine. In 2014 Dr. Weissleder was named by Thomson Reuters as one of the “The World’s Most Influential Scientific Minds”.
