Catherine Stampfl is a theoretical condensed matter physicist with an outstanding international reputation for her investigations into the atomic and electronic structure of solids, their surfaces, interfaces, and nanostructures. She uses accurate first-principles calculations, in conjunction with high-performance computing, to gain fundamental understanding of the behaviour of matter and to predict new and improved materials for technological applications. She has made paradigm-shifting investigations in the area of theoretical surface science and sustained contributions in materials for nanoelectronic devices. Her research field bridges the fields of physics, chemistry, engineering and materials science.
