Robert J. Twiss

Robert J. Twiss is an American geologist emeritus of University of California, Davis. He made his Ph.D. 1971 at Princeton University.[1]

First in his career he researched viscosity of earth mantle.[2] Nowadays he interests for the mechanisms and mechanics of rock deformation and the interpretation of connected structures.[3][4]

Together with geologist Eldridge M. Moores he has co-authored two famous textbooks: Tectonics and Structural Geology.
