Research

Johan's research is conducted mainly at the Laboratory for Laser Energetics at the University of Rochester, National Ignition Facility (NIF) at Lawrence Livermore National Laboratory, and the Z facility at Sandia National Laboratory, studying ICF and HEDP plasmas. At the NIF, he is responsible for several neutron and charged-particle measurements in support of the ignition experiments.

Johan has also pioneered a new field of research, called plasma nuclear science, which blends the disciplines of plasma and nuclear physics. In his pioneering experiment, he demonstrated for the first time that an ICF facility and high-energy-density plasma can be used to study basic nuclear physics. This work was featured in APS Physics.

Johan has authored/co-authored more than 240 peer-reviewed journal papers. He is a member of the APS-DPP Executive Committee (2016-); member of the OLUG Executive Committee (2015-), chairing the ICF-HED National Ignition Implosion Physics working group formed by NNSA (2015-); a member of the National Diagnostic planning effort (2013-); an Executive Committee member for the HTPD conference (2014-); a panel member of the DOE High-Energy-Density Laboratory Physics (HEDLP) ReNew Panel 2009; a member of the NNSA Basic Research Directions on User Science at the NIF panel in 2010; and panel lead for the Stagnation properties and burn panel, which was part of the NNSA Review on Science of Fusion Ignition in 2012. He is a fellow of the American Physical Society (Division of Plasma Physics).
