Thomas F. Rosenbaum, Caltech's ninth president, is the Sonja and William Davidow Presidential Chair and professor of physics.
Dr. Rosenbaum is an expert on the quantum mechanical nature of materials—the physics of electronic, magnetic, and optical materials at the atomic level—that are best observed at temperatures near absolute zero. He conducted research at Bell Laboratories, IBM Watson Research Center, and the University of Chicago before joining Caltech as its president on July 1, 2014.
At Chicago, Dr. Rosenbaum was the John T. Wilson Distinguished Service Professor of Physics, and served as the University's provost for seven years. In that role, he had responsibility for a broad range of institutions and intellectual endeavors across the sciences, arts, and professional schools. He was the University's vice president for research and for Argonne National Laboratory from 2002 to 2006.
Dr. Rosenbaum is an elected fellow of the American Physical Society, the American Association for the Advancement of Science, and the American Academy of Arts and Sciences. He received his bachelor's degree in physics with honors from Harvard University and an MA and PhD in physics from Princeton University.
