Personal profile
Research Interests
We study hydrothermal systems and their relationship to hazards, life, and the green energy transition.
Specifically, our research focuses on fundamental questions such as how hydrothermal ecosystems form, persist and produce critical minerals; how volcanic eruptions and earthquakes initiate and end; and how climate change affects hazards.
