My research interests span in the fields of rock physics, geophysics, and volcanology. In particular, I'm interested in understanding how hydrothermal processes affect the integrity of rocks and find ways to characterize the geophysical signatures of these processes for active monitoring.

- Geophysical signatures of hydrothermal alteration for evaluating volcanic flank instability
Catastrophic collapses of the flanks of stratovolcanoes pose a major hazard threatening human life and property. Many such collapses are triggered by hydrothermal alteration processes that can mechanically weaken the volcanic edifice or favour pressure build-up within the subsurface. How these alteration processes manifest themselves as geophysical signals in volcano monitoring systems is, however, not well understood. This project aims to establish a link between measurable petrophysical properties of variably altered rocks and their corresponding elastic, magnetic and electrical geophysical signatures. The broader goal of this project is to provide a calibration and better understanding of geophysical images acquired over stratovolcanoes in New Zealand and around the world.
- How do hydrothermal alteration processes affect the rock microstructure?
An in-depth understanding of how hydrothermal alteration processes alter the host rocks is vital for monitoring field-scale CO2 sequestration projects and understanding the broader role of such processes in volcanic settings. By performing systematic laboratory experiments this project aims to understand how hydrothermal reaction between ferromagnesian rich rocks like basalts and CO2-rich fluid affect the rock microstructure.
Involvement in other ongoing projects:
- The physical properties of Alpine Fault cataclasites that drive its elastic wave velocities
The Alpine Fault in New Zealand is late in its cycle of stress accumulation and thus provides an exciting opportunity to understand the conditions in the subsurface ahead of a large earthquake. This project aims at characterizing the physical properties of rocks from the Alpine Fault that may control the mechanisms of its rupture and propagation.
- Understanding the pyroclastic phases of the eruption of Rangitoto volcano
Rangitoto volcano is the youngest and largest eruptive center in the Auckland Volcanic Field. This project aims to characterize the different eruption products and understand the pyroclastic phases of its eruption.
