Boulder, Colorado, United States
Summary
👤
Senior🎓
Top SchoolDavid Bruhwiler is an industrial and computational physicist with 30+ years of hands-on experience modeling particle accelerators, plasma dynamics, and radiation systems, and 11 years in leadership roles building RadiaSoft into a hub for cloud-based scientific computing. As co-founder and long-time CEO now serving as Principal Scientist and Chairman, he led development of Sirepo, a browser-accessible CAE gateway that brings accelerator and X-ray simulation tools and integrated JupyterLab to the cloud and into university curricula. His career spans national-lab and industry R&D—contributing to FELs, wakefield accelerators, vacuum and shielding design, and control-system modeling—while routinely marrying first-principles simulation with practical engineering for medical and commercial applications. He combines deep algorithmic expertise (PIC codes, high-order integrators, collision models) with product-minded delivery, helping customers deploy private instances of open-source tools for production engineering. Based in Boulder, Colorado, he is as comfortable mentoring multidisciplinary teams as he is implementing HPC workflows and GUI-driven scientific gateways. A less obvious strength is his sustained focus on making legacy scientific codes accessible via modern web interfaces, enabling wider adoption of advanced simulation in industry and education.
