He started his career in High-Energy physics in 2004, by contribution to the construction of the ATLAS detector at CERN. He obtained his PhD with the University of Oslo and CERN in 2009, after having performed research on electron-positron collider drive beam energy extraction techniques. In 2011 he moved to California for postdoctoral studies at the Stanford Linear Accelerator Center (SLAC), where he, in collaboration with colleagues from UCLA and Stanford University, built up and performed plasma wakefield acceleration experiments at the FACET test-facility. The collaboration demonstrated the first two-beam plasma wakefield acceleration. Professor Adli is currently leading is leading the Norwegian accelerator activities toward the AWAKE and CLIC projects at CERN, towards FACET at SLAC and toward ESS.
