Research Fellow in Geophysics

EarthByte Group


I am a Research Fellow in the EarthByte Group within the School of Geosciences at The University of Sydney. I am an expert in fusing Earth evolution models with data to understand the occurance of enigmatic volcanoes. Related research interests include the cycling of volatiles within the Earth, probabilistic thermal models of the lithosphere to unravel past tectonic and climatic events, and the response of groundwater flow pathways to tectonic forces.

I am a vocal advocate for the integral role of geoscience in responding to challenges we face in transitioning to the carbon-neutral economy. As an expert in my field, I have been interviewed in national and international print media, TV, and radio on a wide variety of subjects including earthquakes, volcanoes, groundwater, and critical minerals.
