Geophysical Exploration of Terrestrial and Lunar Volcanic Fields
(2021)
Planetary analogs are environments representative of current or past conditions on other planetary bodies. My research uses terrestrial volcanic fields as lunar analogs to conduct geophysical studies on the subsurface ...
Characterizing 3-dimensional Melt Distribution and Anisotropic Permeability in Sheared Partially Molten Rocks
(2020)
With increasing shear strain, initially homogeneously distributed melt can segregate into an array of melt-rich bands, flanked by melt-poor regions. To address how the formation of these melt-rich bands affects the transport ...
THE GEOCHEMICAL BEHAVIOR OF SCANDIUM DURING FRACTIONAL CRYSTALLIZATION AND IMPLICATIONS FOR ORE FORMATION
(2020)
Demand for scandium is increasing due to the use of scandium-aluminum alloys in the aerospace and sporting goods industries, and in solid-oxide fuel cells. Scandium deposits are associated with mafic intrusions and laterites, ...
Inference of Mass Anomalies in Planetary Interiors Using a Bayesian Global Gravity Field Inversion
(2020)
Knowledge about the interior density distribution of a planetary body can constraingeophysical processes and reveal information about the origin and evolution
of the body. Properties of this interior distribution can be ...
INSIGHTS TO THE GENETICS, AGE AND CRYSTALLIZATION OF GROUP IC AND IIC IRON METEORITES
(2020)
Siderophile element isotopic compositions and abundances were determined for the IC and IIC iron meteorite groups to assess whether the members of each group can be related by crystal-liquid fractionation models, constrain ...
A prototype miniature mass spectrometer for in situ analysis of trace elements on planetary surfaces
(2021)
Interrogation of the chemical composition of rocky planets provides a deeper understanding of the history and evolution of the solar system. While laboratory studies of returned samples and remote sensing surveys of planetary ...
Petrologic, Geochemical, and Spectral Characteristics of Oxidized Planetary Differentiation
(2021)
Meteorites provide evidence that planetary formation occurred across a wide range of oxidation environments in the early Solar System. While the process of differentiation for many reduced, oxygen-poor assemblages has been ...
GENETICS, AGES, AND CHEMICAL COMPOSITIONS OF IRON METEORITES
(2020)
Comparison of genetic isotopic compositions of iron meteorites with metal-silicate segregation ages suggests that the isotopic composition of the NC reservoir changed with time. By contrast, no such age-linked changes in ...
BRITTLE FAULTING IN POROUS, WATER-SATURATED SANDSTONE DEFORMED UNDER HIGH PORE FLUID PRESSURE
(2020)
The effective stress law is widely used to model the deformation of crustal rock. It states that effective pressure, the difference between confining pressure and pore fluid pressure, dictates rock strength. In low-porosity ...
TRACKING TRANSPORT OF ‘CHEMICAL COCKTAILS’ OF TRACE METALS USING SENSORS IN URBAN STREAMS
(2020)
Understanding transport mechanisms and temporal patterns in metals concentrations and fluxes in urban streams are important for developing best management practices and restoration strategies to improve water quality. In ...
