I take a multi-disciplinary approach to understand volcanic processes, combining computational skills (GIS, Python, MATLAB), laboratory analysis (SEM, EMPA, melt inclusions, mineral chemistry, stable isotopes), and field geology to address questions concerning 1) the physical scale and measurement of volcanic processes 2) the chemical processes controlling valuable metal concentrations in magmas.

Big Data Perspectives on the Behavior of Copper in Arc Magmas

In order to determine which magmatic processes control copper (Cu) abundance in the crust, we compiled a global, multi-factor database of arc magma chemistry, geology, and tectonics. Our model provides an example of the power of Big Data to determine fundamental processes in petrology.

Metals in Magmas: Intra-Arc Variations in Volcanic Metals in East Java, Indonesia

I am leading a regional survey of magmatic chemistry in volcanoes across Java, Indonesia. This work combines textural, microanalytical, and isotope analyses in melt inclusions, individual minerals, and whole rock, to better constrain 1) the timing of sulphide vs. vapor saturation in magmas and 2) the optimal tectonic conditions for crustal Cu deposition. I developed this project in partnership with Universitas Gadjah Mada researchers based in Yogyakarta, ID.

How Big Is a Flood Basalt? Calculating the Volume of the Deccan Traps

We compiled and digitized existing geographic data on the thickness and extent of the Deccan Traps, using geographic information systems (GIS) and geostatistical tools to determine the pre- and post-erosional areas and volumes of lava packages. The goal is to provide a geospatially-grounded volume estimate that can inform accurate paleoclimate reconstruction in the Late Cretaceous.

Tiltmeter Observations at Axial Seamount

Axial Seamount is the most active submarine volcano in the NE Pacific, located ~300 miles west of the Oregon Coast with a summit depth of 1500 meters. This project aimed to analyze the 3+ years of Ocean Observatories Initiative (OOI) tiltmeter data recorded before, during, and after the 2015 eruption to better understand the internal plumbing system at the volcano, using MATLAB software to visualize the caldera’ 3D deformation. This work has implications for improving monitoring forecasts at marine volcanoes.
