I study small bodies of the solar system with particular emphasis on meteors, meteorites, meteoroids, and asteroids.
I am interested in answering basic questions about the origin and evolution of small bodies in the solar system. These include:
The origin of metoroids (comets/asteroids/interstellar and what proportion of each?)
Origin of meteorites (asteroid belt, mostly, but where specifically?)
Physical structure of meteoroids (bulk density/dustballs - what does this say about their origin?)
Flux and interaction of larger meteoroids at Earth (meteorites, breakup in the atmosphere)
