Johan's research is conducted in the areas of High-Energy-Density-Plasmas (HEDP), Inertial Confinement Fusion (ICF), and Inertial Fusion Energy (IFE). Together with his students, he is building and using a wide range of diagnostics in 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. He has initiated collaborations with Commonwealth Fusion Systems, Pacific Fusion, and Focused Energy in the private sector. 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 340 peer-reviewed journal papers. He was elected member of the Executive Committee for the High Temperature Plasma Diagnostics (HTPD) conference in 2014; member of the Scientific Advisory Board for Institute of Laser Engineering Osaka University in 2023; member of the Executive Steering Committee for the National Diagnostic Planning effort, initiated by the National Nuclear Security Administration (NNSA) (2014-2023); and member and co-chair of the Executive Committee of the Omega Laboratory Users Group (2016-2023). 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 has received several awards, including the APS’s John Dawson Award for Excellence in Plasma Physics Research in 2022; the Fusion Power Associates Leadership award in 2023; the Department of Energy Secretary's Honor Award in 2021, 2022 and 2023; the Defense Programs Award of Excellence for exceeding Lawson’s criterion for ignition in 2023. He is a fellow of the American Physical Society (Division of Plasma Physics).
