Dr. James (Jimmy) Juno is a Staff Research Physicist in the Computational Sciences Department here at the Princeton Plasma Physics Laboratory. At PPPL, Jimmy is part of the core development team for the Gkeyll simulation framework and works on a variety of computational plasma topics spanning fusion and astrophysical sciences. His responsibilities include the maintenance and continued development of the one-of-a-kind multi-species, continuum Vlasov-Maxwell solver within Gkeyll, and he is actively involved in the cross-platform improvements in performance and robustness which affect the other core solvers of Gkeyll, such as the gyrokinetic solver and multi-fluid methods. He is currently actively developing the capabilities of Gkeyll to model relativistic plasmas as part of PPPL’s extreme astrophysics initiative, as well as supporting new capabilities of the gyrokinetic solver for axisymmetric simulations of fusion reactors, a kinetic analogue of fluid codes such as SOLPS-ITER. Before joining PPPL, Jimmy was a NASA Earth and Space Sciences Fellow (now the FINESST program) at the University of Maryland, where he completed his doctoral work under the supervision of Professor William (Bill) Dorland and Dr. Jason TenBarge, and he was a NSF Atmospheric and Geospace Sciences Postdoctoral Research Fellow at the University of Iowa under the mentorship of Professor Gregory (Greg) Howes.
