Norman H. Sleep

Professor of Geophysics


(650) 723-0882



Professor Sleep applies heat and mass transfer to physical processes within the Earth. He studies convection at the base of the lithosphere and the interaction of the lithosphere with mantle plume material. Hot plume material locally thins the lithosphere and ponds within preexisting regions of thin lithosphere. He is also investigating the microphysics of friction. He is currently applying the results to nonlinear attenuation and ground damage by strong seismic waves. He is also considering pre-photosynthetic sources of energy for life (like hydrogen from serpentine and methanogenesis) and the effects of photosynthetic ecology on surface and tectonic processes.
