Projects:
I study all kinds of meteorites to help solve problems in planetary science. Primitive meteorites called chondrites help us understand how the solar system formed. Our goal is to understand how a disk of dust and gas evolved into a collection of planets, moons, asteroids and comets. Chondrites are extraordinarily diverse. Metal-rich chondrites contain more metal from the hottest parts of the disk and less dust from the coolest parts than any other type of chondrite and may resemble the material from which the planet Mercury accreted. Relating chondrites and planets will help us understand how both formed and whether Earth-like planets may be common around other stars. I also study metamorphosed chondrites and igneously formed meteorites to learn how planetary bodies were heated, melted and differentiated. Martian meteorites offer great insights into the geological evolution of Mars and its water content. I have focused on unraveling the effects of alteration and impacts on ALH84001 and infer that evidence for life has yet to be discovered in this rock. I study shock effects in all kinds of meteorites to understand how these rocks were modified by impacts, where they come from and how they got here. These studies use optical and scanning electron microscopy and electron probe analysis and benefit greatly from collaborations with colleagues in HIGP and elsewhere.
