An observational seismologist by training, I am interested in understanding seismic waveform complexities at very high frequency, generated by dynamic natural hazard processes and fine-scale structural heterogeneities in Earth's subsurface. I model and simulate waveforms to study volcanic sources, debris flows, earthquake waveforms in complex environments, from sedimentary basins to core-mantle boundary.

At ANU-RSES, I deploy Distributed Acoustic Sensing (DAS), a new generation fibre-optics based seismic array, at places from rural outbacks to urban metropolitans, transforming how scientists can image the subsurface and detect natural hazard processes at an unprecedented spatio-temporal resolution.
