Career Research Highlights


My central interest is in dynamics of earthquake rupture. I am exploring the rupture process using tools like laboratory experiments, numerical modeling and field geology. One of the main questions I am trying to answer is what is the frictional behavior of faults during the fast and short earthquake slip episodes? How can it affect the rupture propagation and hazardous seismic radiation? I order to shed light on these questions I started to work several years ago with scientists from different backgrounds. We created an international group with specialties ranging from field structural geology and microstructures of faults, laboratory methods to deform rocks at high speed and analytical/numerical methods to help upscale the results from the small scale of the lab (rock samples of a few cm) to the large scale (natural seismic fault dimensions can reach tens of kilometers).
