Mao Receives 2007 Inge Lehmann Medal



The Inge Lehmann Medal is awarded in recognition of “outstanding contributions to the understanding of the structure, composition, and dynamics of the Earth's mantle and core.” When Ho-kwang (Dave) Mao completed his Ph.D. in 1968 at the University of Rochester and moved to the Geophysical Laboratory, a revolution in how we could achieve that understanding was in the making.

Over the following four decades, Dave Mao redefined solid Earth geophysics, demonstrating that the mantle and core are accessible in the laboratory through direct study of their components at high pressures and temperatures. Through diverse, ingenious experimentation, this journey to the center of the planet has revealed the many dramatic ways that Earth materials transform under extreme conditions and established a materials-based understanding of the deep interior.
