Seismology at LDEO

Lamont is home to one of the world’s strongest and most diverse research programs in seismology.  Lamont seismologists are at the forefront of theoretical and observational seismology, rock mechanics, and solid earth dynamics, and are making lasting contributions to the study of earthquakes, the structure of the Earth’s crust, mantle, and core, the dynamics of magmatic systems, and the large-scale motions and deformation of the Earth’s surface.  We are always interested in recruiting talented and energetic graduate students, post-doctoral scholars, and undergraduate interns.  Please contact me or visit these web pages for further information:

My Research

I use seismic imaging to gain a better understand of the dynamic processes in the mantle that drive surface deformation and volcanism. We are exploiting tremendous new data from EarthScope, as well as data that we collect in innovative land- and sea-going field experiments. Current projects include mantle flow and melting associated with hotspot volcanism, the role of magmatism in the development of new plate boundaries in East Africa and the Gulf of California, and nature of the San Andreas fault at mantle depths.
