Lee Bernstein is the Nuclear Data Group Leader at LBNL and the UC-Berkeley Department of Nuclear Engineering whose mission is to meet the nuclear data needs of the applied and basic science and engineering community while training the next generation of nuclear scientists and engineers in the process. He has over 25 years of experience in experimental nuclear physics with a specialization in measuring low-energy nuclear properties and cross sections. Lee has led domestic and international experimental campaigns on GB to TB data sets using high-resolution charged-particle, neutron and photon spectrometers. Prior to coming to LBNL in 2016 he was a staff scientist at Lawrence Livermore National Lab where he served as the Deputy Group Leader for the Nuclear Diagnostics Group at the National Ignition Facility and helped lead the development of detectors to measure the properties of HED plasmas. He is a fellow of the American Physical Society “For work developing novel methods of determining neutron-nucleus cross sections via high-resolution gamma-ray spectroscopy, the early development of surrogate ratio method, and the study of nuclear processes in high energy density plasmas at NIF”. Lee is also an adjunct faculty member in the UC-Berkeley department of nuclear engineering where he has taught courses in nuclear physics and policy and has served as the principal academic advisor for 12 Ph.D. and M.S. students.
