Summary
👤
Senior🎓
Top SchoolJohan Carlsson is a computational plasma physicist and Theory & Simulation Architect with nine years of professional experience building high-performance simulation software in C/C++ and Python, and fluency in Fortran and Java. He specializes in particle-in-cell and kinetic simulations for novel fusion concepts, having developed tools like the orbitrappist integrator and led the mooser bounce-averaged Fokker-Planck project to bridge PIC and long-timescale collisional modeling. At Avalanche Energy he has combined hands-on code development, team leadership, and project management while collaborating with national labs such as Sandia and maintaining an independent R&D practice. Comfortable working across platforms from 8-bit microcontrollers to supercomputers, he brings rigorous applied-math instincts and a multidisciplinary background (including engineering physics and Russian studies) that help him translate complex theory into practical, production-grade simulation tools.
