Summary
👤
Senior🎓
Top SchoolBryce Kalmbach is a project scientist and scheduler software engineer with 12 years of experience building algorithms and high-performance software for the Vera C. Rubin Observatory and the LSST. Based at SLAC after several years at the University of Washington, he focuses on active optics, scheduler development, simulations, machine learning, and HPC to turn massive sky surveys into actionable science. His work spans practical tasks like detecting faint Solar System objects with GPU-accelerated pipelines to cosmological survey simulations used by LSST DESC, where he co-convenes the Cosmological and Survey Simulations Working Group. Bryce combines deep academic training—a PhD in Physics—with hands-on software engineering to bridge research and production systems for large-scale astronomical datasets. He brings a talent for translating statistical and ML methods into scalable tooling that operates under real-world observing constraints. Based in Seattle, he pairs domain expertise in astronomy with a developer’s focus on robust, high-throughput implementations.
