Biography

Thomas H. Jordan is a University Professor and the W. M. Keck Foundation Professor of Earth Sciences at the University of Southern California. His current research is focused on system-level models of earthquake processes, earthquake forecasting, continental dynamics, full-3D waveform tomography, and seismology. He is an author of approximately 260 scientific publications, including two popular textbooks (with J. Grotzinger) Understanding Earth, 7th ed. and The Essential Earth, 2nd ed.

As the director of the Southern California Earthquake Center from 2002 to 2017, Jordan coordinated an international research program in earthquake system science that involved over 1000 scientists at more than 70 universities and research organizations. In 2006, he established the international Collaboratory for the Study of Earthquake Predictability and, since 2006, has been the lead SCEC investigator on projects to create and improve a time-dependent Uniform California Earthquake Rupture Forecast. He is a member of the California Earthquake Prediction Evaluation Council.

He has served as a member of the Council of the National Academy of Sciences (2006-2009) and the Governing Board of the National Research Council (2008-2011). He chaired the NRC panels that produced two decadal reports, Living on an Active Earth: Perspectives on Earthquake Science (2003) and Basic Research Opportunities in Earth Sciences (2002).

Jordan received his Ph.D. from the California Institute of Technology in 1972 and taught at Princeton University (1972-1975) and the Scripps Institution of Oceanography (1975-1984) before joining the Massachusetts Institute of Technology in 1984. He was head of MIT’s Department of Earth, Atmospheric and Planetary Sciences from 1988 to 1998. In 2000, he moved from MIT to USC, and in 2004, he was appointed as a USC University Professor.

He has been awarded the Macelwane and Lehmann Medals of the American Geophysical Union, the President’s Medal and Woollard Award of the Geological Society of America, and the 2012 Award for Outstanding Contribution to Public Understanding of the Geosciences by the American Geosciences Institute. He is a fellow of the American Association for the Advancement of Science and the American Geophysical Unionand has been elected to the National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society.
