Prof. Dr. Ingo Steinbach is a pioneer of the phase-field theory with early publications from 1996. His Multi-Phase-Field approach, with contributions from many other scientists worldwide, forms a standard for multi-phase application in metallurgy and other fields of materials research. Applications range from pattern formation during solidification over solid-state transformation during materials processing to materials degradation and failure. He recently went back to the roots of the phase-field theory in non-linear wave mechanics to propose a Quantum Phase Field Concept of Matter, which forms a new paradigm for understanding the physical world. Hesham Salama is a Research Associate and a PhD student under the supervision of Prof. Steinbach in the context of the phase-field theory. He is one of the developers of the OpenPhase software project targeted at numerically maximum efficient phase-field simulations.
