CONSTRAINTS ON THE LITHOSPHERIC STRUCTURE OF MID OCEAN RIDGES FROM OCEANIC CORE COMPLEX MORPHOLOGY
(2016)
The Mid-oceanic ridge system is a feature unique to Earth. It is one of the fundamental components of plate tectonics and reflects interior processes of mantle convection within the Earth. The thermal structure beneath the ...
Evolution of strength and physical properties of ultramafic and carbonate rocks under hydrothermal conditions
(2016)
Interaction of rocks with fluids can significantly change mineral assemblage and structure. This so-called hydrothermal alteration is ubiquitous in the Earth’s crust. Though the behavior of hydrothermally altered rocks can ...
The Role of Water and Strain Rate in the Deformation of Limestone
(2017)
Fluids are pervasive throughout the Earth’s crust. Fluid-rock interaction can significantly alter the mechanical and petrophysical properties of host rocks. This study focuses on the role of fluids in weakening porous ...
Characterization of the regional, crustal, and global distribution and abundance of the heat producing elements and their geoneutrino flux
(2019)
The amount and distribution of radiogenic power generation from the heat producing elements (HPE) U, Th, and K in the Earth is not well constrained. Compositional estimates of these elements vary by a factor of three in ...
Planetary Seismology using Single-Station and Small-Aperture Arrays: Implications for Mars and Ocean Worlds
(2020)
Studying geophysical station deployment on Earth is essential preparation for future geophysical experiments elsewhere in the solar system. Here, I investigated how single-station seismometers and small-aperture seismic ...
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 ...
THE SEDIMENT AND CRUSTAL STRUCTURE OF THE SOUTHEASTERN UNITED STATES
(2019)
The Southeastern United States (SEUS) preserves a detailed geologic record of the continental collision and rifting that has shaped it over billions of years. Currently the SEUS lies on a passive margin far away from ongoing ...
DEFORMATION AND FAILURE OF LUNAR LAVA TUBES
(2021)
Lava tubes are long void spaces left by lava flows. Terrestrial tubes have been extensively studied. Evidence indicates lunar tubes also exist, potentially ideal environments for lunar exploration, habitation, and study. ...
DYNAMIC MELT PROCESSES IN THE LITHOSPHERES OF MARS AND IO
(2020)
The interior structures of planetary bodies beyond the Earth are broadly unknown. Our observational capacity is largely limited to surface imagery from spacecraft. The work presented in this dissertation uses novel modeling ...
APPLYING GEODESY TO MODEL POSTSEISMIC SLIP OF THE 2016 MW 6.4 MEINONG EARTHQUAKE
(2019)
In regions of rapid convergence such as southwest Taiwan, unmapped active structures at multiple depths increase the uncertainty of seismic hazard estimates. The 2016 Mw 6.4 MeiNong earthquake occurred below the main Taiwan ...
