Research Professor, Climate and Space Sciences and Engineering
Center for Space Environment Modeling
Dr. Toth works on algorithm and code development for space and plasma physics simulations. He has a leading role in the development of the Space Weather Modeling Framework (SWMF) that can couple and execute about a dozen different space physics models modeling domains from the surface of the Sun to the upper atmosphere of the Earth. He is one of the main developers of the BATS-R-US code, a multi-physics and multi-application magnetohydrodynamics code using block-adaptive grids. He is collaborating with many colleagues and students using the SWMF and BATSRUS for a wide range of applications: solar corona, coronal mass ejections, magnetic storms, comets, moons (Titan, Enceladus), planetary magnetospheres (Earth, Venus, Mars, Jupiter, Saturn), interaction of moons with their plasma environment (Titan, Enceladus), interaction of comets with the solar wind, outer heliosphere interaction with the inter-stellar material, etc. The SWMF is used by the Community Coordinated Modeling Center (CCMC) at NASA Goddard for research as well as real-time forecasting of space weather. Dr. Toth was also the software architect for the Center for Radiative Shock Hydrodynamics (CRASH). This DoE funded center worked on modeling radiative shocks created by high energy lasers and the uncertainty quantification of the model results. He has designed and implemented of the Versatile Advection Code, a general purpose publicly available hydrodynamics and MHD code. VAC has been used by hundreds of researchers around the world to simulate various hydrodynamic and MHD problems.
