Introduction
I am an igneous petrologist with experience in experimental petrology, planetary geology, and mantle geochemistry. My previous and ongoing work focuses on the chemical evolution of planetary interiors. My upcoming work will also focus on determining the economic viability of reprocessing mine waste for critical metals.

Description
- Studying the effects of magma mixing on the petrologic evolution of boninite lavas from the Izu-Bonin subduction system. This involves trying to figure out what controls mixing in this system and how that might relate to changes in plate motion.

Early subduction zone volcanism, magma mixing, and mineral zoning textures.
This Preliminary Report is an IODP publication that summarizes the scientific and technical accomplishments of IODP expedition 391: Walvis Ridge Hotspot: drilling Walvis Ridge, Southeast Atlantic Ocean, to test models of ridge hotspot interaction, isotopic zonation, and the hotspot reference frame (6 December 2021–5 February 2022).

Valdivia Bank (VB) is a Late Cretaceous oceanic plateau formed by volcanism from the Tristan‐Gough hotspot at the Mid‐Atlantic Ridge (MAR). To better understand its origin and evolution, magnetic data were used to generate a magnetic anomaly grid, which was inverted to determine crustal magnetization. The magnetization model reveals quasi‐linear po...
Hybridization of the lunar mantle during the overturn (sinking) of Fe- and Ti–rich ilmenite-bearing clinopyroxenite cumulates (IBC) in the lunar interior is called upon to explain the high TiO2 abundances of lunar basalts. Chemical reactions that occur after juxtaposition of IBC and mantle peridotite are poorly constrained. We experimentally invest...
To investigate the role of Plag floatation efficiency on the formation of depleted Eu/Eu* signatures in lunar mantle sources, we model the fractionation of Eu in LMO mantle cumulates assuming different Plag floatation efficiencies. To calculate Eu fractionation during LMO solidification and subsequent melting, we develop new fO2-dependent Eu partit...
The concentrations and distribution of heat producing elements (HPEs) (K, U, and Th) within planetary interiors determine thermal evolution. Previous studies conclude that the Moon is K depleted and U and Th enriched relative to chondritic meteorites; however, to our knowledge, estimated abundances of HPEs have not been tested in the context of rec...
The past ∼200 million years of Earth's geomagnetic field behavior have been recorded within oceanic basalts, many of which are only accessible via scientific ocean drilling. Obtaining the best possible paleomagnetic measurements from such valuable samples requires an a priori understanding of their magnetic mineralogies when choosing the most appro...
International Oceanic Discovery Program (IODP) Expedition 391 recovered core from basalts from four sites along the Walvis Ridge hotspot track, a chain of ridges and seamounts extending southwest off the coast of Namibia. The purpose of the expedition is to document the evolution of the Walvis Ridge hotspot, as well as understand the volcanology of...
Introduction: Cumulate mantle overturn is hypothesized to be a consequence of lunar magma ocean (LMO) solidification, where dense late stage cumulates composed of ilmenite (Ilm) and clinopyroxene (Cpx) sink into less dense underlying cumulates in Rayleigh-Taylor instabilities [1-5]. As the sinking Ilm and Cpx experience adiabatic compression, inter...
Introduction: Ilmenite-bearing cumulates (IBC) are thought to precipitate from a lunar magma ocean (LMO) after ~90%-98% solidification [1, 2]. IBC contain silicates (Cpx and plagioclase) and Fe-Ti oxides (e.g., ulvöspinel and ilmenite), giving them high density with respect to underlying cumulates. This gravitationally unstable density stratificati...
Cumulate mantle overturn is hypothesized to be a consequence of lunar magma ocean (LMO) solidification [1-5]. As dense ilmenite (ilm) bearing cumulates (IBC) sink through the lunar mantle and radiogenically heat, they will eventually pass their solidus and begin to melt. Melting the IBC would produce a Ti-rich ferrobasalt that reacts with the surro...
Subduction is the geologic process in which one tectonic plate moves beneath another as it sinks into the Earth’s mantle. Subduction initiation in the Izu-Bonin Marianas system is the result of a gravitational failure during which one tectonic plate (the Pacific plate) spontaneously sinks beneath another (the Philippine Sea plate). Fluids released...
