Mark Panning often has a difficult time writing about himself in the third person, but will give it a try for the sake of his office-mate who is arranging these brown bag seminars. Mark did not discover an interest in the geosciences until taking a summer field geology course on a whim as an undergraduate at Indiana University. He did some undergraduate research looking at seismic refraction and ground penetrating radar surveys of the (strangely land-locked) Crane Naval Surface Warfare Center in southern Indiana, but decided he wanted to work on a much larger scale (as well as in a more active geologic setting). He went to graduate school at UC Berkeley, where he primarily worked with Barbara Romanowicz developing a global anisotropic shear velocity model of the mantle. He finished his thesis work in 2004, and did some continuing postdoctoral work at Berkeley, continuing work on new techniques for seismic imaging as well as working with Michael Manga and others on a proposed study of seismology on Jupiter's moon Europa. Since September 2006, he has begun work as a Council on Science and Technology teaching postdoctoral fellow. He is currently working with Guust Nolet and Tony Dahlen with a focus on integrating different datasets for improved tomographic models, while also working on updating the large lecture class GEO210B to make it more interactive using new technologies.
