Summary
👤
Senior🎓
Top SchoolStephen Dewitt is a computational scientist with a decade of experience building high-performance continuum simulation tools for complex materials systems, currently working at Oak Ridge National Laboratory and as a research investigator with the PRISMS Center at the University of Michigan. He leads development of the open-source PRISMS-PF phase-field framework and applies it to link microstructural phenomena—like precipitate evolution, grain growth, and corrosion—to macroscopic properties in magnesium alloys. His background blends rigorous PhD-level modeling of electrochemical and nanostructured systems with hands-on HPC implementations, including custom parallel Fortran codes and scalable phase-field solvers. Stephen’s work sits at the intersection of computational materials science and additive manufacturing, enabling predictive materials design rather than purely descriptive studies. Colleagues value his ability to translate theoretical multiphysics models into production-grade, community-facing software that accelerates both research and engineering.
