Summary
🤩
Rockstar🎓
Top SchoolJohn Coleman is a computational scientist at Oak Ridge National Laboratory specializing in simulation of transport phenomena during materials processing, with a PhD in Materials Engineering from Purdue and three years of postdoctoral and staff experience. His work blends advanced numerical modeling and high-performance simulation—rooted in his dissertation on equiaxed solidification and contributions to OpenFOAM solidification tools—to tackle casting and solidification challenges. He has industrial experience from internships and projects with Alcoa, U.S. Steel, and Steel Dynamics that inform practical, process-focused modeling decisions. Based in Knoxville, Tennessee, he brings a strong bridge between academic rigor and applied metallurgical engineering, often translating complex multiphysics into usable insights for manufacturing processes.
