Educational Background:

2004 - present Arizona State University (Tempe, AZ) , PhD candidate
1998 - 2004 Diplom (Magna Cum Laude) in Geology (minor: Geophysics, Hydrogeology), Thesis: “Paleoseismic Investigation along the Laikipia-Marmanet-Escarpment, Subukia Valley, Kenya.”

 

Research Interests:

Earthquake geology, numerical earthquake simulations, paleoseismology, active tectonics, and tectonic geomorphology; interaction of complex fault systems and its effect on seismic behavior  (e.g., magnitude-frequency distribution, slip distribution); the San Andreas Fault system; earthquake recurrence models; transition from passive to active continental margin and vice versa; crustal deformation; friction laws and their implementation in earthquake simulations; fault growth and off-fault deformation

 

Awards and Honors:

2007 Outstanding Student Paper Award, presentation at the 2007 AGU Fall Meeting in San Francisco, CA. Title: “Effect of fault roughness on scaling relationships among earthquake magnitude and rupture characteristics.”
