Biography and CV

Professor Johnson's research can be broadly categorized as materials characterization at the intersection of mechanical engineering and materials science. The thrust of his effort is to under-stand macroscopic material behavior in terms of its microstructure and to develop material models that accurately capture the response of a wide range of materials. His recent work falls into four areas: 1) microscopic modeling of failure modes in brittle materials, 2) understanding the failure of materials under impact loading, 3) developing macroscopic material models for the large-deformation response of metals, and 4) application of X-ray tomography with micron-level resolution to visualize the growth of damage in structural materials. Professor Johnson is also currently the Chair of the Board on Admissions and Relations with Schools (BOARS), a committee of the systemwide Academic Senate for the University of California.
