I am working with colleagues to bring scientific computing to the cloud. As a computational physicist and software executive, with expertise in high-performance modeling of intense particle and radiation beams, laser pulses, plasmas and associated technologies, I am committed to the benefits of open source software and of technical collaboration for science and society.
