Jacob is currently the Lurie Family Professor of Radiology at Harvard Medical School and a Phyllis and Jerome Lyle Rappaport MGH Research Scholar. He also serves as Scientific Director of the Lurie Center for Autism and Director of Radiochemistry at the Martinos Center for Biomedical Imaging, both at Mass General Hospital. He received his PhD in Chemistry from the University of California, Berkeley in 2007 working with Prof. Matt Francis. Dr. Hooker then completed two fellowships—a Goldhaber Distinguished Fellowship and a Ruth Kirschstein Fellowship—with Dr. Joanna Fowler at Brookhaven National Laboratory, where he maintained an appointment as an Associate Scientist through 2013. In 2009, Dr. Hooker moved to Boston to join the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital. There he co-founded and co-directs a first-in-class imaging facility that merges functional MRI and positron emission tomography for neurochemical study of the human brain. Dr. Hooker holds associate appointments at the Broad Institute and Massachusetts Institute of Technology (MIT). He currently serves as Editor-in-Chief of ACS Chemical Neuroscience. Further information on Dr. Hooker and his research can be found on the Martinos Center Chemical Neuroscience Program website.
