Background:

I am originally from Orange County, California. My interest in the earth sciences began began after the 1971
earthquake in Sylmar, California tossed
me from my bed. I was introduced to plate tectonics the following year and was hooked on earth science for life.
I received my Bachelor of Science Degree in Physics from Princeton University in 1979, where I worked as a go-fer
in the geology department. I gave my first talk at an AGU meeting in 1980, arguing against a theory that large
earthquakes could cause observable changes in the Earth's rotation axis. I received my Doctorate in
Earth Sciences in 1985 from the University of California, San Diego. From 1985-1986, I did a post doc at
Princeton University and from 1986 I have been on the faculty of Yale University.

Offices Held:

· (2008-2011) Director, Yale Institute for Biospheric Studies

· (2002-2008) Chairman, Environmental Studies Program, Yale College

· (2005-2007) Chairman, Standing Committee of the IRIS Global Seismographic Network

· (2000-2002) President, Seismology Section of the American Geophysical Union

· (2002-2004) Member of Governing Board, American Institute of Physics (AIP)

· (1992-1994) Chairman of Executive Committee, Incorporated Research Institutions for Seismology (IRIS)

Current Research:

· Mapping mantle flow associated with plate tectonics, using seismic anisotropy. SEE picture.

· Using scattered seismic waves, and seismic anisotropy, to infer aligned cracks and rock fabrics in the crust.

Teaching Philosophy

I like to advise students who have an active curiosity, and give them a lot of freedom to define
projects that capture their interest. However, I try to start a student on a small well-defined
initial project so that he or she can produce something interesting in a reasonable amount of
time and gain some perspective on possible dissertation projects. Students of mine with good
quantitative and computer skills have often found themselves presenting talks at meetings after a few months of research.
