At PlasmaSpectraConsulting AB and Lund University, I build optical diagnostic systems, real-time sensing hardware, and process specifications for high-temperature industrial environments, clean energy applications, and reactive thermal flows.

I've led EU consortium work packages, authored 16 peer-reviewed publications, and taken R&D from multiphysics modeling and optical-rig design through experimental testing and data analysis. My work spans laser diagnostics, plasma physics, inline instrumentation, CFD/MHD simulation, and industrial furnace temperature monitoring.
