Seth Stein (President-elect)
AGU member since 1976. Deering Professor of Geological Sciences, Northwestern University, Evanston, Ill.Volunteer experience includes AGU duties serving as JGR editor, Seismology program chair for the Fall Meeting, Seismology and Geodesy section committees for recommending AGU Fellows, and chairing the Bucher Medal and Excellence in Geophysical Education Award committees. I have served on medal committees for the EGU and GSA, panels for NSF, NASA, the European Science Foundation, German Science Foundation, and European Research Council, and on advisory committees for departments in the U.S. and abroad.

Much of my research explores how earthquakes result from tectonic processes at the boundaries of plates and within them, and how limitations in our understanding of these processes affect our ability to forecast earthquake hazards. Because similar challenges arise for other natural hazards, I am interested in general questions of estimating uncertainties in hazard forecasts, assessing how well they work, and developing mitigation strategies that that make societal and economic sense, given limited resources and limited knowledge about what the earth will do.
