Biographical Sketch

Johan's research is conducted in the areas of High-Energy-Density-Plasmas (HEDP), Inertial Confinement Fusion (ICF), and nuclear physics. Together with his students, a wide range of diagnostics are built and used to support of the ICF programs 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, as well as to conduct basic science experiments at these facilities. In addition, Johan has 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 270 peer-reviewed journal papers. He was elected a member of the Executive Committee for the High Temperature Plasma Diagnostics (HTPD) conference in 2014; the Executive Steering Committee for the National Diagnostic Planning effort, initiated by the National Nuclear Security Administration (NNSA) (2014- ); and member and co-chair of the Executive Committee of the Omega Laboratory Users Group (2016- ). He was also chairing the ICF-HEDP National Ignition Implosion Physics (NISP) Working Group, an effort initiated by NNSA in 2015-2018; 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).
