　　简  介：Simon L. Klemperer is Professor of Geophysics, and of Geological & Environmental Sciences, at Stanford University. Klemperer earned his bachelor’s degree at Cambridge University, and his PhD at Cornell University. Both his PhD and subsequent post-doctoral research at Cambridge applied multichannel seismic reflection methods to the exploration of the continental lithosphere and to the investigation of deep tectonic processes. Since 1992, Klemperer has been studying the Himalaya-Tibet orogen, first with the INDEPTH program of seismic and magnetotelluric studies in Xizang and Qinghai, and more recently collaborating with SINOPROBE to record and interpret reflection profiles. Since 2015 Klemperer has collaborated with ITPCAS to use noble-gas geochemistry to probe the state of the upper mantle beneath Tibet and this presentation will show first results of that collaboration. Klemperer’s recent interests also include the cratonic structure of the Ordos Plateau; mantle earthquakes in Saudi Arabia; and neotectonic vertical motions of the San Andreas fault system offshore southern Califronia. Klemperer is a fellow of both the Geological Society of America and the American Geophysical Union.
