Berkeley Lab’s Associate Laboratory Director for Physical Sciences champions the highly-accomplished research divisions in accelerator technology, engineering, nuclear science, particle physics and cosmology. Appointed ALD in July 2020, Natalie Roe received her PhD in Physics in 1989 from Stanford University. She joined the Lab as a postdoctoral fellow and held positions as Staff Scientist, Senior Scientist and Physics Division Director prior to taking on the ALD role. Roe has developed advanced instrumentation for her research in particle physics, and more recently for cosmology experiments designed to study dark energy and the early universe. As Director of the Physics Division, Roe oversaw an expansion of research into dark matter, dark energy and quantum information science. Roe is a Fellow of the American Association for the Advancement of Science and the American Physical Society, and has served as president of the APS Division of Particles and Fields, as well as numerous national and international advisory committees. She was a founding member of Berkeley Lab’s Women Scientists and Engineers Council (WSEC) and is an executive sponsor of the Lab’s Early Career Employee Resource Group.
Cameron Geddes, an award-winning scientist known internationally for his work on laser-plasma accelerators, is Division Director, Accelerator Technology & Applied Physics Division.
Geddes earned his PhD in physics from the University of California, Berkeley in 2005. His graduate work was recognized with the APS-DPP’s Marshall N. Rosenbluth Outstanding Doctoral Thesis Award, as well as the Hertz Foundation Dissertation Prize. Further recognition for his achievements has included the U.S. Particle Accelerator School Prize, the American Physical Society Division of Plasma Physics (APS-DPP) John Dawson Award for Excellence in Plasma Physics Research, and Fellowship in the APS.
Before his appointment as Division Director, Geddes served as the Berkeley Lab Laser Accelerator (BELLA) Center’s Deputy Center Director for Experiments. He oversaw the diverse experimental portfolio within the BELLA Center, which develops plasma accelerators to extend the energy frontier of future high-energy physics experiments and for photon sources and applications. He most recently led the creation of a quasi-monoenergetic gamma-ray source that can bring new capabilities to nuclear security applications (as well as medical and industrial imaging) based on compact laser-plasma accelerators. He continues to serve as leader of the Laser-Plasma Accelerator Applications Group within the BELLA Center, as well as the next-generation kBELLA initiative.
Henrik von der Lippe was appointed Engineering Division Director in the Physical Sciences Area on March 30, 2016. He is also the Authority Having Jurisdiction for Safe Electrical Equipment, and manages the Electrical Equipment Safety Program at LBNL.
As Engineering Division Director, Henrik von der Lippe is responsible for aligning and deploying the Division’s unique design, technical fabrication, mechanical and electrical engineering, integrated circuit, and operational expertise with the scientific objectives and strategic priorities of the Lawrence Berkeley National Laboratory. There are over 230 skilled and experienced employees contributing to significant advancements in scientific instrumentation, research, and development.
Throughout his career of more than 15 years at the LBNL, von der Lippe has served in a number of technical and organizational leadership roles in the Engineering Division. Before assuming his current role as Division Director, Mr. von der Lippe was the Department Head for Electronics, Software & Instrumentation Engineering. Henrik von der Lippe is distinguished by unique achievements in custom integrated circuit (IC) design, and has led the IC group at Berkeley Lab since 2000.
Von der Lippe received a Master of Science degree in Electronic Engineering with a concentration in IC design from the University of Oslo in Norway. Prior to working at Berkeley Lab, von der Lippe fulfilled a number of engineering and managerial roles at Tandberg Data ASA and SINTEF in Oslo, Norway.
Barbara Jacak is a senior faculty scientist and the director of the Nuclear Science Division at Berkeley Lab. She is also a professor in the physics department at the University of California (UC), Berkeley. Jacak was one of the founding members of the Pioneering High Energy Nuclear Interaction eXperiment (PHENIX) at the Relativistic Heavy Ion Collider, and was the experiment’s spokesperson from 2007 to 2012. Before joining PHENIX, she was active in CERN’s heavy ion program as a member of the Helios and E844 collaborations. She has been very active in the development of the national nuclear physics program and served on the Nuclear Science Advisory Committee’s Long Range Plan for Nuclear Science working groups in 1995, 2001, and 2006. She is a fellow of the American Physical Society and the American Association for the Advancement of Science, and is a member of the National Academy of Sciences.
A leading figure of the nuclear physics community in the United States, Jacak’s personal research focus is on the experimental study of the quark-gluon plasma. She completed her undergraduate studies at UC Berkeley, and her Ph.D. at Michigan State University (MSU), where her advisor was David K. Scott. After graduating from MSU, she received an Oppenheimer Fellowship at Los Alamos National Laboratory, and remained on the staff there until January 1997. She then joined the faculty at the State University of New York at Stony Brook as a professor of physics, and was promoted to distinguished professor in 2008.
