Summary
👤
Senior🎓
Top SchoolRyan Sandberg is a transformational physicist and computational scientist with 11 years of experience building exascale plasma and beam simulation software and modeling advanced particle accelerator concepts. With a PhD in Applied and Interdisciplinary Mathematics from the University of Michigan and postdoctoral work at Berkeley Lab, he has contributed to high-impact open-source projects like WarpX—enhancing diagnostics, RZ mode support, and data output for large-scale PIC codes. He pairs deep theoretical knowledge of laser-plasma physics and numerical methods with practical C++/Python and GPU programming expertise, and has applied ML workflows to accelerate surrogate modeling and design optimization. Now at Northrop Grumman, he brings interdisciplinary collaboration, teaching-honed communication skills, and a knack for turning complex differential-equation problems into reliable, production-ready simulation tools. An understated strength is his ability to move between three distinct roles—physicist, applied mathematician/software developer, and educator—making him effective at both research and engineering integration.
