Robert J. Twiss is an American geologist emeritusofUniversity 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^{[citation needed]} textbooks: Tectonics and Structural Geology.
