Dr. Fischer is renowned for her research on Earth’s upper mantle dynamics, the structure and evolution of continental lithosphere, and the dynamics of subduction systems. Over her career she has clearly made “outstanding contributions to the understa...

Few scientists’ work can honestly be claimed to have transformed the perception of how Earth works. If a picture is worth a thousand words, then it is true that Steve Grand’s tomographic images clearly resolving the subducted Farallon slab penetratin...

Jean-Paul Montagner is a pioneering and influential seismologist who has made fundamental contributions to seismology, especially for the study of Earth’s deep interior and dynamics through his work on seismic anisotropy. The birth of digital seismol...

Uli Christensen is one of the unique individuals who have contributed to both domains of core and mantle and as such is a fitting recipient of the Lehmann Medal. It is rare for an individual to have had such a level of impact in both domains of geody...

Yoshio Fukao is a deep thinker with influential ideas who has made outstanding observational and theoretical contributions to solid Earth geophysics using seismological tools. He has been a leader on imaging of subducted slabs in the mantle transitio...

Brian Kennett’s innovations in theoretical seismology, as well as his profound and ­wide-­ranging observational studies, have had a lasting impact in geodynamics and geochemistry and have significantly improved the practice at international dat...
