Lunar Chronology & Geochemistry
I have multiple ongoing research projects involving Apollo samples. In particular, I am interested in understanding the nature of early lunar magmas, the chronology of impact bombardment, and the record of regolith processes that influence the lunar crust.
Terrestrial Impact Structures
Impact cratering is a fundamental process on all planetary bodies in our solar system. Terrestrial impacts provide an analog with which we can study the cratering process and the ways that these extreme environments influence sample chemistry and chronology.
Many of the chemical systems and analytical techniques used in cosmochemistry are relevant for nuclear forensics investigations. I am interested in understanding the noble gas signatures of underground explosions and the methods for detecting these signatures.
