Biography

I currently am a Schmidt AI in Science Fellow at the Department of Earth Sciences at the University of Oxford, investigating AI methods for seismic imaging of the Earth’s inner core.

Recently, I was a postdoc in the Seismology & Mathematical Geophysics group at RSES at ANU, looking at estimating continental-scale sediment thickness with passive seismic methods, and regularisation approaches in geophysical imaging.

I completed my PhD in Data Intensive Science at UCL in 2022. My research focused on solving large-scale inverse imaging problems using probabilistic methods, applied to seismological and cosmological problems.

Interests
