Summary
🤩
Rockstar🎓
Top SchoolMatt Rolchigo is a materials science researcher and computational modeler with six years of experience applying high-performance computing to simulate microstructure evolution in metal additive manufacturing. Currently at Oak Ridge National Laboratory after a postdoc at Lawrence Livermore, he specializes in cellular automata solidification models, MPI parallelization, and GPU acceleration via Kokkos, and has integrated codes with CFD tools like OpenFOAM and Truchas. His work bridges theory and large-scale simulation, collaborating across national labs and universities to quantify how melt-pool conditions and uncertainties drive grain growth and texture. Matt’s background ranges from experimental particle synthesis to injection-molding simulations, giving him a rare combination of hands-on lab experience and production-grade scientific software development. He holds a PhD in Materials Science and Engineering from Iowa State and is based in Knoxville, Tennessee.
