Research Interests

My work focusses on the recurrence of large and potentially destructive earthquakes.  I want to help answering questions such as: What parameters control the timing and size of earthquakes? How is the occurrence of earthquakes along a fault characterized? Are earthquakes predictable and if so, in which way or form?

To address these questions, I use observational data from paleoseismology and tectonic geomorphology, providing critical information about a fault’s past rupture behavior. Additionally, I develop and apply numerical tools that incorporate the current understanding of rupture process and earthquake cycle (e.g., multi-cycle earthquake rupture simulators). Using this approach, I generate long sequences of earthquakes to analyze, among other aspects, the recurrence of large earthquakes. I am particularly interested in learning how the complexity of fault geometry and the spatial distribution of rupture-controlling parameters along the fault surface affect earthquake recurrence and its predictability.
