Low-temperature magnetized plasmas are found in many systems, including plasma processing, space weather, and spacecraft propulsion. Two phenomena that are poorly understood in cross-electric and magnetic field plasma sources, such as magnetrons and Hall effect thrusters, are: (i) self-organized structures and (ii) anomalous electron transport across the magnetic field lines. In this talk, I will present the development of physics-based modeling, including fluid moment models and high-fidelity kinetic models, to address these processes. The fluid moment model coupled with improved boundary condition treatments is applied to low-temperature magnetized plasmas. The particle-based kinetic models are used to investigate multidimensional plasma turbulence initiated by a combination of kinetic instabilities in cross-field configurations. I will also introduce datadriven modeling using optimization and state estimation techniques applied to dynamical plasma systems.
