Profile Summary

David Bruhwiler is president, CEO, and Chairman of the Board at RadiaSoft LLC, a startup that he co-founded in 2013. His scientific work in the areas of parallel computing, charged particle acceleration, X-ray optics, nonlinear integrable phase space dynamics, laser-plasma and beam-plasma interactions, electron cooling of ion beams, advanced accelerator concepts and solar physics has produced 55 refereed articles (including two in the Nature series and 3 in Physical Review Letters), 15 invited talks at international conferences, one patent and over 100 other scientific reports and conference proceedings. A Fellow of the American Physical Society and a Senior Member of the IEEE, he regularly reviews funding proposals for the US Department of Energy, Office of High Energy Physics, Office of Basic Energy Sciences and Office of Advanced Scientific Computing Research, as well as the National Science Foundation. He routinely reviews articles for Physical Review (Letters, E, Special Topics AB), Physics of Plasmas and IEEE Transactions. Dr. Bruhwiler’s scientific successes include: key contributions to early simulations of quasi-monoenergetic beams from laser-plasma accelerators, the concept of a self-ionizing plasma wakefield accelerator, contributions to initial simulations of the patented Trojan horse concept for producing electron beams of unprecedented brightness, and fundamental improvements to the understanding and use of parametric models for dynamical friction – essential to the next generation of electron-ion colliders for nuclear physics. He is now working to bring scientific computing to the cloud via the open source Sirepo framework, https://sirepo.com, leveraging software investments of the US Department of Energy to stimulate advanced manufacturing and bolster the US economy, and also to educate the next generation of particle accelerator scientists and engineers.
