Research Interests
      My research is primarily focused on modeling earthquakes, and understanding the short term and long term behavior of  faults. Using, strong-motion, teleseismic and geodetic data, what can we tell about the slip in a single earthquake, rupture velocity, slip functions? How can we compare the long term coupling to slip in individual earthquakes.  

       For Masters and Ph.D opportunities do not hesitate to contact me through e-mail. We welcome students from all fields of engineering, physics and mathematics as well as geophysics.
