I am a seismologist. Our group studies how earthquakes start, propagate and stop, with seismic array imaging (back-projection), joint seismic and geodetic finite-fault inversion, and numerical modelling. Recent work includes a global survey of supershear earthquakes, the 2023 Türkiye, 2024 Noto and 2025 Mandalay earthquakes, tsunami source inversion, and methods for checking machine-learning earthquake catalogues.
Research
All topicsRupture physics & supershear
How fast ruptures run, and why some outrun the shear waves: Palu, Mandalay and a global census.
02Back-projection imaging
Tracking high-frequency radiation with seismic arrays: MUSIC, slowness calibration, 3-D and PKIKP back-projection.
03Finite-fault & joint inversion
Slip on multi-segment faults from seismic, GNSS and InSAR data: Maduo, Türkiye, Noto, Mandalay.
04Tsunami
Rapid source characterisation by back-projection, time-reversal and adjoint inversion, and fast surrogates.
05Swarms, slow slip & fibre sensing
Fluid-driven swarms, foreshocks and afterslip, and distributed acoustic sensing (DAS).
06AI for geoscience
Phase picking, verifying machine-learning catalogues, and agent-based seismological workflows.
