Member of international group which first measured the directional anisotropy of ~1014eV galactic cosmic rays
With Russian colleagues, first to establish that during solar minimum conditions energetic electrons originating from the solar wind are responsible for maintenance of Venus' nighttime ionosphere
Pioneer in modern cometary plasma physics development
Pioneer in modeling of the complicated physical process controlling the interface region between the comet nucleus and the continuously escaping cometary coma
With colleagues, developed first-time dependent model of the terrestrial polar wind, which accounted for the dynamics and energetics of the transonic ion outflows from the high-latitude ionosphere
Derived new transport equations from higher-order velocity moments of the Boltzmann equation using a non-isotropic Gaussian base-function
Currently leading a computational Grand Challenge Investigation team developing a new generation of high-performance 3D MHD codes using solution adaptive grids
