Professor Tullis' interests lie in the investigations of the deformation mechanisms, microstructures, and rheology of crustal rocks have been conducted over a wide range of conditions, equivalent to those from the shallow to the deep crust and upper mantle, and including deformation processes from brittle fracturing to cataclastic flow to dislocation creep to melt or fluid–enhanced diffusion creep and grain boundary sliding. In addition she has investigated the influence of the chemical environment on deformation and the mutual interactions of deformation, phase changes, and fluid distribution.
