My research is focused on understanding volatiles in planetary interiors, with a current focus on nitrogen and nitrogen-bearing phases. I use high-pressure and high-temperature experimental methods to recreate planetary interior conditions so as to study volatile-containing phases in-situ using a variety of analysis techniques. My work aims to better understand how volatiles are incorporated into planetary mantles (both in the Earth and in other planets), as well as how planetary interiors are connected to the surface atmosphere composition through outgassing processes.

My research focuses on processes that occurred in the primitive Earth, during the period when core-mantle differentiation was ongoing. This is the era of the Earth’s history when major chemical reservoirs were established and the Earth acquired its bulk physical properties. I study the chemistry of different groups of elements through experiments carried out at high temperature and pressures using the laser-heated diamond anvil cell. This apparatus is capable of simulating the extreme conditions that existed in a deep terrestrial magma ocean. The results of these experiments are applicable to questions regarding terrestrial planet formation, bulk compositions and volatile accretion.
