Dr. Lee Josephson received his B.S. in chemistry from the University of Wisconsin and his Ph.D. in chemical biology from the State University of New York at Stony Brook. He was a post-doctoral fellow in the laboratory of Dr. Guido Guidotti at Harvard University and a cofounder of AMAG Pharmaceuticals (AMAG, AMEX), where served as Chief Scientific Officer from and supervised the development of magnetic nanoparticles as FDA approved MR contrast agents. He joined the Center for Molecular Imaging Research at Massachusetts General Hospital in 1997 and was a cofounder of T2 Biosystems in 2006. Dr. Josephson’s interest in the design of magnetic materials for biomedical applications led to the initial patents and publications demonstrating that the combination of magnetic nanoparticles and T2 NMR detectors could yield improved tests for the clinical laboratory. He is currently an Associate Professor at Harvard Medical School, and a member of the Center for Advanced Molecular Imaging Sciences (CAMIS) and the Martinos Center for Biomedical Imaging at MGH.
