Current Research Interests:

I study space weathering (what is space weathering?) and the ways in which space weathering affects the visible/nearIR spectra of soil. Space weathering affects all bodies which are not protected by an atmosphere. I have been studying lunar soils for a while now to understand the processes involved in space weathering. The Moon is a great place to start because we actually have samples from the Moon to study. Beyond that I am also trying to apply this knowledge to the asteroids and Mercury to understand how space weathering on these bodies will be similar/ different than on the Moon. Why do we care about space weathering? Because until we have samples in hand of the rest of the Moon and Mercury and the asteroids (well, we have meteorites, but we don't know which asteroids they come from) our information must come from remote methods (satellites, rovers, telescopic data, etc.). Space weathering processes create the soil that covers the surface of these bodies and alters its properties. Therefore, if we want to understand the data that we recieve from these remote methods, we must understand the weathering processes.
