My research interests centre on earthquake physics, seismic hazard assessment and earthquake resilience. I combine physical and stochastic numerical modeling of earthquake processes that I confront with seismological observations. I am particularly interested in understanding the mechanisms by which earthquakes trigger other earthquakes (e.g. in damaging earthquake cascades or fluid-injection induced seismicity) and in improving models for the probabilistic forecasting of future earthquake potential, including probabilistic seismic hazard assessment (PSHA). I lead the global Collaboratory for the Study of Earthquake Predictability (CSEP), which provides cyberinfrastructure for prospective and reproducible evaluations of earthquake forecast models around the globe. Current work focuses on earthquake clustering and forecasting, fault-based seismic hazard assessment in the Himalaya and Malawi, fluid-injection induced seismicity and machine-learning based approaches to earthquake seismology.
