Search for Ultralight Bosonic Dark Matter

Professor Derek F. Jackson Kimball’s research uses techniques of experimental atomic physics and nonlinear optics for precision tests of the fundamental laws of physics. In particular, his research focuses on searches for exotic spin-dependent interactions that may have a connection to dark matter or dark energy. Recent work focuses on development of levitated ferromagnetic torque sensors, devices that promise to greatly enhance sensitivity to spin-dependent interactions. He coordinates two international collaborations searching for ultralight bosonic dark matter fields: the Global Network of Optical Magnetometers for Exotic physics searches (GNOME) and the Cosmic Axion Spin Precession Experiment (CASPEr). Prof. Jackson Kimball earned his Bachelor’s degree in Physics and Mathematics in 1998 and his Ph.D. in 2005, both at the University of California at Berkeley under the mentorship of Prof. Dmitry Budker, with whom he has collaborated throughout his career. In 2005,he joined the faculty of California State University – East Bay where he has mentored more than 70 undergraduate research students, and published three books and over 80 research papers. He was named Cal State East Bay’s Outstanding Professor in 2012, elected an APS fellow in 2018, received the 2019 Spitzer Distinguished Science Faculty Award, and awarded the 2022 APS Prize for a Faculty Member for Research in an Undergraduate Institution.  Professor Karl van Bibber received his BS and PhD from MIT in experimental nuclear physics. After postdoctoral work at LBNL, he served as an Assistant Professor of Physics at Stanford. He joined LLNL where he founded and led the High Energy Physics and Accelerator Technology Group, and was LLNL Project Leader for construction of the SLAC-LBNL-LLNL PEP-II B Factory project. His institutional service includes positions as Chief Scientist for the Physics and Space Technology directorate, and Deputy Director of the Laboratory Science and Technology Office. In 2009 he became Vice President and Dean of Research of the Naval Postgraduate School in Monterey, CA. In 2012 he joined the faculty of UC Berkeley as Professor and Chair of Nuclear Engineering, serving also as Executive Director of the Nuclear Science and Security Consortium, a DOE Office of Non-Proliferation center-of-excellence. In July 2017, he was appointed Associate Dean for Research in the College of Engineering. His research focuses on basic and applied nuclear science, particle astrophysics, and accelerator science and technology. He is the recipient of an Alfred P. Sloan Research Fellowship, the DOE Deputy Secretary Award for the SLAC-LBNL-LLNL PEP-II B Factory accelerator, and the Navy Superior Civilian Service Award for the establishment of degree and executive education programs in Energy, the first within the DoD. He is a fellow of the APS and AAAS. His research in particle astrophysics focuses on dark matter axion searches, and searches for the axion in general.
