Rockstar🎓
Top SchoolCharles Kawczynski is a Principal Scientist and research software engineer with 12 years applying high-performance and parallel computing to climate modeling, computational fluid dynamics, and magnetohydrodynamics. He holds a PhD in Mechanical Engineering from UCLA where he built and optimized large-scale MHD simulation codes (including a code-generator that produced a third of his group’s Fortran) and discovered dramatically accelerated liquid-metal flow behavior under plasma-disruption–like fields. At CliMA and Caltech he led GPU-accelerated efforts using CUDA to make climate and physics simulations faster and more scalable, and now drives modeling and simulation at Code Metal. Charles blends numerical analysis, PDE expertise, and software engineering best practices to deliver production-ready scientific codes while mentoring cross-disciplinary teams. He’s known for squeezing performance out of challenging problems—achieving millions-to-tens-of-millions-of-unknowns solves at production rates—and for fostering open communication and continuous learning in engineering teams.
