Dust Dynamics - how does it move?  Where does it come from and go?  What concerns are there to missions to dusty places like the Moon and asteroids?

Exoplanets - determining properties of planets orbiting stars other than our own sun.

Laboratory Astrophysics - spectroscopic studies of astrophysical dust analogs and constituents of planetary atmospheres.

Planetesimal Formation - studying the formation of planetesimals through experiments and numerical simulations.

SL9 Impacts Jupiter - building the first self-consistent, 3D computer model of all phases of the event.

Saturn's Rings - structure, dynamics of the rings using Cassini's UVIS data and simulations.
