About Me

I am Assistant Professor of the Department of Earth, Atmospheric and Planetary Sciences at the Massachusetts Institute of Technology. My research focuses on understanding the diversity of earthquakes and the associated ground motions expected on the surface of the Earth.

I received my PhD from Scripps Institution of Oceanography at UC San Diego working with Peter Shearer and Frank Vernon on scaling properties of earthquakes using state-of-the-art signal processing on some of the largest datasets at the time. I was a Thompson Postdoctoral Fellow at Stanford University working on seismic tomography and ground motion predictions using the ambient seismic field. Prior to my appointment at MIT, I was a faculty member and head of the new Geosciences program at Universidad de los Andes and a Visiting profesor at IPGP in 2012

My main interest is to use seismic records to understand the earthquake source, the interior of the Earth and how both affect the ground motions that we feel on the Earth's surface. Seismological observations are affected by the internal structure of the Earth, for example amplification of seismic waves in sedimentary basins. The nature of the earthquake source has also a significant impact on ground motions, and I am interested in a better understanding of earthquake ruptures, i.e., are large earthquakes different from the more common small ones?
