Jeff Reimer received his bachelor’s degree (with honors) from the University of California at Santa Barbara, and his doctorate from the California Institute of Technology. After his postdoc at IBM Research in New York he joined the Berkeley faculty where he is presently the C. Judson King Endowed Professor and the Warren and Katharine Schlinger Distinguished Professor and Chair of the Chemical and Biomolecular Engineering Department. Professor Reimer has won the UC Berkeley Distinguished Teaching Award, the highest award bestowed on faculty for their teaching. His research generates new knowledge for environmental protection, sustainability, and provides fundamental insights to condensed matter via materials chemistry, physics, and engineering. He is recognized for these works by election as a Fellow of the American Association for the Advancement of Science, a Fellow of the American Physical Society, and a Fellow of the International Society for Magnetic Resonance. In 2015 he received a Research Fellowship from the Alexander von Humboldt Foundation.  In addition to his research publications, Professor Reimer is co-author (with T.M. Duncan) of the introductory text Chemical Engineering Design and Analysis (Cambridge University Press, 2nd edition, 2019), and the text Carbon Capture and Sequestration (with Berend Smit, Curt Oldenburg, Ian Bourg, World Scientific Press, 2013).
