Dr. Darren Bleuel has a diverse experimental nuclear physics research background with a particular focus on cross-disciplinary fields like nuclear-plasma-atomic interactions, biological effects of radiation, laser-induced nuclear reactions, and astrophysical nucleosynthesis. He also has extensive experience performing a wide variety of accelerator-based experiments involving gamma-ray spectroscopy in coincidence with particle identification, as well as neutronics simulations using MCNP. The vast majority of his work has, in some way, involved neutrons.

He received both his bachelor’s and Ph.D. in nuclear engineering from the University of California (UC) at Berkeley, designing an optimal moderated neutron spectrum for Boron Neutron Capture Therapy. He then served as a postdoctoral researcher at the Lawrence Berkeley National Laboratory (LBNL) developing a deuteron-breakup facility at the 88-Inch Cyclotron. Subsequently, as a postdoc at Lawrence Livermore National Laboratory, he developed and led the neutron activation diagnostic program at the National Ignition Facility, which provided the first indication of implosion asymmetries. He became a full-time staff physicist at Lawrence Livermore National Laboratory in 2007 and currently researches both direct and indirect neutron cross section measurements, neutron imaging, reactions networks of short-lived fission products, and nuclear-plasma interactions. He collaborates extensively with LBNL and UC Berkeley, notably through the construction of GENESIS, a new facility for measuring inelastic cross sections at LBNL's 88-inch cyclotron, as well as the University of Oslo, Ohio University, Michigan State University (FRIB), and iThemba LABS.
