Within the broader field of geospace science, my main research focuses on system-level studies of the interaction between the solar wind, magnetosphere, ionosphere and upper atmosphere, including neutral dynamics, plasma electrodynamics, magnetohydrodynamics (MHD), and collisionless transport processes, with applications to space weather forecasting. I am also interested in the development of high-performance computing based, general purposed multi-dimensional models of solving the MHD equations for extended research applications, including but not limited to, geospace, planetary magnetospheres, inner heliosphere, solar corona and basic plasma simulations. 

With my research collaborators, I am currently working on the development of a coupled whole geospace model for space weather research, simulation models for ionospheric outflows into the magnetosphere; the effects of magnetosphere-ionosphere coupling on the global geospace dynamics; the dynamics of co-rotation dominated magnetospheres such as Jupiter and Saturn; and high-order numerical schemes for solving the MHD equations.
