About Me

I am an Assistant Professor of Geophysics at the Department of Earth, Atmospheric and Planetary Sciences (EAPS) at the Massachusetts Institute pof Technology (MIT). Previously I was a Thompson Postdoctoral Fellow at the Geophysics Department, Stanford University. I received my Ph.D and M.Sc. in Earth Sciences from the Scripps Institution of Oceanography (UCSD) and my B.Sc. in Geology from the National University in Colombia.

My research focuses in understanding the physics of earthquakes, how and why earthquakes occur, how they grow to become large damaging processes and what to expect of the ground motions on the surface of the Earth. As an observational seismologist I analyze large amounts of seismic data in order to test predictions from physically based models, allowing me to draw conclusions about fundamental questions in seismology. For example, by stacking hundreds of spectra I was able to show the similarity of earthquake rupture regardless of the size or magnitude of the events. I have been involved in using non-earthquake (ambient noise) data to investigate the ground motions of possible future earthquakes. More recently I have shown that it is also possible to extract the anelastic structure (attenuation) of the Earth from the ambient seismic field. In my research I develop advanced analysis techniques to answer these and other relevant questions.
