I use physics models and machine learning for my research in volcanoes, earthquakes and groundwater systems.
My research group tackles some big challenges that arise when managing extreme groundwater systems in a safe and sustainable way. Steam-driven volcanic eruptions - we use machine learning techniques to identify seismic signals that suggest an imminent eruption from shallow hydrothermal systems. Using this, we have developed a real-time warning system for Whakaari.Human-triggered earthquakes - we model how fluid injection and extraction in hydrocarbon projects changes stress on faults. By matching the rate of earthquakes in the past, we can predict the future earthquake rate for different operation styles.Geothermal reservoir imaging - we study the interaction of solar electromagnetic signals with the Earth to understand where, how large and how powerful our geothermal systems are.Carbon sequestration - we use models to demonstrate safe and efficient ways to pump large amounts of CO2 underground so that it doesn't contribute to climate change.
