Bill Spotz is an experienced computational scientist and founder with 22 years building and managing large-scale scientific computing programs across national labs and the U.S. Department of Energy. He blends deep technical expertise—demonstrated by contributions to core projects like NumPy, where he improved wrapper generation and array support—with program management skills that guided funding and strategy for computational research. Bill led technical teams at Sandia National Laboratories and managed SciDAC centers at DOE, translating advanced numerical methods and multiphysics modeling into mission-driven outcomes. Now based in Albuquerque, he runs Spotz Scientific while teaching mathematics at the University of New Mexico, bridging research, education, and entrepreneurship. His background includes a PhD in Aerospace Engineering from UT Austin and a track record of shipping robust, tested code as well as shaping national research priorities. An uncommon mix of hands-on open-source development and high-level program stewardship makes him effective at turning complex scientific requirements into practical, supported software.
