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.
NZ’s gas shortage was not caused by the offshore exploration ban – but it was still a flawed policy

Historically, gas in New Zealand traded below NZ$10 per gigajoule. When prices hit $50 per gigajoule in August this year, anyone with gas to sell could have made a lot of money. But there clearly wasnt much gas around....
Green hydrogen could decarbonise entire industries in NZ – but there’s a long way to go
Nov 25, 2024 23:41 pm UTC| Insights & Views Business
Hydrogen has been called the Swiss army knife of decarbonisation because it can do many things. But not all of them make sense. Today, the world uses about 100 megatonnes of hydrogen per year (MT/y), but this is...
