Research Interests

Earthquake geology (analyzing geomorphic and stratigraphic expressions of earthquake surface rupture, aiming to constrain slip accumulation patterns and earthquake recurrence intervals along a fault to determine its earthquake recurrence characteristics an potential for earthquake predictability and forecast), Numerical earthquake simulations (running multi-cycle earthquake rupture simulations --in a forward-modeling sense --to analyze the effect of specific model parameters on seismic fault behavior --e.g., effect of fault-geometric complexity or depth-dependent of fault strength on magnitude-frequency distribution and earthquake recurrence characteristics), Kinematic earthquake rupture models (seismic source inversion that utilizes a range of data sets from real earthquakes to resolve respective fault slip history and final slip distribution on finite fault planes)
