Associate Director of Science for Nuclear Physics

Timothy J. Hallman

Dr. Timothy J. Hallman has served as the Associate Director for Nuclear Physics of the Office of Science since November 23, 2009. With an annual budget of over $500 million, the Office of Nuclear Physics is the Nation's leading supporter of fundamental research and facilities in nuclear physics. The mission of the Office of Nuclear Physics is to discover, explore, and understand all forms on nuclear matter. The fundamental particles that compose nuclear matter--quarks and gluons--are relatively well understood, but exactly how they fit together and interact to create different types of matter in the universe is still largely not understood. The Office of Nuclear Physics supports experimental and theoretical research--along with the development and operation of particle accelerators and advanced technologies--to create, detect, and describe the different forms and complexities of nuclear matter that can exist in the universe, including those no longer naturally found. In addition, the Office of Nuclear Physics administers the Isotope Development and Production for Research and Applications program which develops and produces isotopes for use around the world.

Previously, Dr. Hallman served as Senior Scientist at Brookhaven National Laboratory (BNL) where he led the group responsible for the operation of the Solenoidal Tracker At RHIC (STAR) Detector, an investment of approximately $100 million in basic nuclear science research by the DOE Office of Science and international partners at the Relativistic Heavy Ion Collider at BNL. From 2002 to 2008, Dr. Hallman served as Spokesperson for the STAR Collaboration, during which time close to 100 nuclear scientists received Ph.D.s and 70 papers were published in refereed journals related to the discovery of a new form of matter resembling a perfect liquid.

Dr. Hallman received a Ph.D. in physics from the Johns Hopkins University for research performed at the Lawrence Berkeley National Laboratory Bevalac particle accelerator on the possibility of a phase transition in nuclear matter under extreme conditions of density and temperature. His early research also included pion and muon capture studies at the Tri-University Meson Facility (TRIUMF) in Vancouver, British Columbia and spin physics research at the BNL Alternating Gradient Synchrotron. Dr. Hallman has been involved in numerous international collaborations. From 2003-2008 he served as Chairman of the Program Advisory Committee for Particle Physics of the Joint Institutes for Nuclear Research (JINR) in Dubna, Russia. In 2009, he was elected to membership on the JINR Scientific Council. He holds honorary degrees from the University of Science and Technology of China, Central China Normal University, the JINR, and Dubna International University. He is a fellow of the American Physical Society and a member of the Johns Hopkins Society of Scholars.
