Kaj Johnson has B.S. and M.S. degrees in Mathematics and Structural Geology from Purdue University, and a PhD in Geophysics from Stanford University. He works primarily with geodetic data and numerical and analytical models to investigate how deformation within plate boundary zones is accommodated by faulting and folding in the upper crust, and by viscous flow in the lower crust and upper mantle. His current research topics include: mountain building in Taiwan; afterslip and fault friction; relationship of interseismic and postseismic deformation to lithosphere rheology; and probabilistic inverse theory.

Meghan S Miller is a structural seismologist with research focus on the interactions between upper mantle convection and surface geology, in particular the role of subduction and continental dynamics. Dr. Miller obtained her PhD in 2006 at the Australian National University and was a post-doc at Rice University and the University of British Columbia, before joining the faculty of the University of Southern California in 2009. She has studied mantle dynamics on a range of spatial scales, including plate boundary systems of the Caribbean and the western Pacific, the lithospheric structure beneath the western U.S., and the core-mantle boundary. Dr. Miller employs a range of methods to address dynamical questions, from plate tectonic reconstructions, seismic tomography and receiver functions, to field studies. Her broadband seismometers are currently deployed in Morocco as part of a collaborative study of the westernmost Mediterranean. Dr. Miller's teaching interests include seismology, with focus on hands-on data analysis, tectonics, and visualization.

Gary Pavlis received his B.S. degree in Engineering Physics from South Dakota State University and his PhD from the University of Washington in Geophysics. He joined the faculty of Indiana University in 1983. His research has spanned a range of topics including seismic imaging at a wide range of scales, applications of precision location techniques in seismotectonics and nuclear monitoring, array processing, and computational seismology. Dr. Pavlis has been involved in a long list of seismic experiments using IRIS instrumentation, including one or more experiments nearly continuously since 1990. His current work with EarthScope is focused on using Transportable Array data to produce high-resolution images of the upper mantle by employing a scattered-wave, three-dimensional method he recently developed, and integrating the images with other EarthScope results.

Harold Tobin was first awed by the scale of plate boundary fault processes during summer fieldwork while completing his B.S. in Geology and Geophysics at Yale University in 1987. This led him to a literal plunge into the deep sea trenches for graduate school, and he completed his doctoral work at the University of California, Santa Cruz in 1995. After a postdoc at Stanford University, he joined the faculty of New Mexico Tech for 9 years. His research is focused on integrating fault geology with geophysical observations through the integration of laboratory petrophysical study of rock samples, borehole logging data, seismic reflection imaging, and structural analysis of fault materials. Dr. Tobin has worked extensively on offshore subduction zone faults during seven ocean drilling expeditions and two Alvin diving cruises, as well as onshore on the San Gregorio and San Andreas faults in California. He is currently torturing core samples from the San Andreas Fault Observatory at Depth (SAFOD) in the laboratory and is also serving as Chief Project Scientist for IODP’s NanTroSEIZE program, one of SAFOD’s sister projects in fault zone drilling. In 2006, Dr. Tobin moved to the University of Wisconsin at Madison, where he thrives despite being about as far from an active plate boundary as one can get.

After receiving his high school diploma in Davis, California in 1970, Steve Wesnousky attended university with the main aim of throwing little white balls over a little white plate. Recognizing that such an activity might not lead to a long-lived career (and subsequent to experiencing a slide show of volcanoes to the music of Jimi Hendrix), Steve decided that geology might hold some promise. So in 1975 he obtained a B.A. in Geology from the University of California at Santa Barbara. Attracted by the potential to play basketball on the streets of New York City, Steve then enrolled in the graduate program at Columbia University and it’s Lamont Doherty Geological Observatory. He played a few good games and received his PhD in Seismology in 1982. Since that time Steve has blended the geological and seismological disciplines to examine problems in seismic hazard analysis, fault mechanics, and active tectonics. He has been fortunate in his career to serve as the President of the Seismological Society of America from 1995-1997, receive Fulbright Scholarships for overseas studies in 1997 and 2005, be accorded recognition as a Foundation Professor at the University of Nevada-Reno, and be recognized as the university’s most outstanding teacher in 2008.
