Solid-Earth Processes | Rock-Fluid Interactions | Subsurface Characterization

I'm a solid-earth scientist pursuing highly ambitious and interdisciplinary research to investigate and monitor the dynamic subsurface of high-risk active volcanoes, fault zones, and natural and man-made reservoirs. Using multi-disciplinary methods from across rock physics, geophysics, geomechanics, geochemistry, and paleomagnetism my previous research has found novel insights explaining the dynamic processes at play for two active volcanoes in New Zealand, the Alpine Fault, as well as carbon-dioxide sequestration sites. Particularly my research has shown mechanisms leading to pre-eruptive pressure-build up at volcanoes, established links between geological processes and their geophysical signatures to aid monitoring of hydrothermally altered regions, shown the complex interplay between hydrothermal alteration and dome stability, characterized the mineralogy and fracture network at active fault zones, and explained the rock structural changes that can occur due to carbon-dioxide sequestration in volcanic reservoirs.

The tools I have used so far involve lab based and computational methods for measuring various rock properties of interest to answer a wide range of questions. Specifically, these include lab-based petrophysical and geophysical rock characterization (e.g., porosity, permeability, P-S- wave velocities, XRD, XRF, X-ray maps, EBSD, ICPMS, EDS, EPMA, thin sections, micro-CT, magnetic susceptibility, NRM), computational methods (e.g., limit equilibrium methods). I'm always on top of learning new tools that can help my research and have obtained certifications in using space/airborne analytical techniques like InSAR for natural hazards research and completed a micro-credential in machine learning methods.

I'm always open to exploring new research questions that can help better characterize and monitor the earth’s dynamic subsurface environments. I also enjoy participating in science outreach events and making science accessible to all.

Current Areas of Research

These are currently a small section of areas I am spending time actively researching.

Rock-Fluid interactions

How do rock-fluid interactions change the properties of rocks? How can we utilize our knowledge on rock-fluid interactions to develop environmental solutions (e.g. carbon capture and storage)? How can we actively monitor changes in the subsurface permeability and chemistry related to rock-fluid interactions?


Hydrothermal Alteration

How does hydrothermal alteration change the physical and chemical properties of rocks in various tectonic settings? What are the implications of these changes on volcanic hazard and fault zone characteristics?


Rock Behavior Under Stress

How do rocks behave under various temperature and pressure conditions? How does this behavior affect fluid flow and deformation? How can we best connect laboratory and field data with modeling to understand the implications of rock behavior in different settings (e.g., volcanic edifices, fault zones) ?

Schematic showing how a partially sealed hydrothermal system can form at Whakaari volcano. Net dissolution of lavas promotes fluid flow but net secondary mineral precipitation and inelastic pore collapse in the tuffs restricts fluid flow.

Hazard Assessment and Monitoring

How do geohazards develop and evolve at high-risk volcanoes? How can we assess and monitor these dynamic hazards at societally relevant timeframes?
