Research Interests
Planetary Science and Cometary Physics
Observation and modeling of the spatial and velocity distribution of neutral and ionized cometary gases and dust
Development of time-dependent multidimensional multispecies fully kinetic models for cometary and planetary satellite atmospheres using Direct Simulation Monte Carlo methods
Planetary satellite atmospheric structure, escape and interaction with planetary magnetospheres: Io, Europa, Enceladus
Mars’ exosphere and atmospheric escape
Venus’ exosphere
Cometary X-ray observations and study of the excitation mechanism
First applied Monte Carlo models to study the complicated geometries of free-flow region of cometary atmospheres
Provided one of the early sets of cometary radical scale lengths for use in determining gas species production rates in comets
First quantitative observations and analysis of the spatial distribution of water and carbon monoxide ions in the heads and inner tails of comets
With a colleague, provided the complete self-consistent description tying together the underlying physics of the dynamics of the inner cometary coma outflow, dominated by water photochemistry, with the appearance and velocity distribution of the hydrogen coma of comets, and how these change with the size of the comet and its distance from the sun
Part of the group that was the first to simulate cometary X-ray production by charge exchange excitation
With colleagues, demonstrated conclusive evidence from ground-based images of comet Hyakutake that fragments of the nucleus traveling down the tail were providing an extended source of gases which collided with the main coma outflow
