Summary
👤
Senior🎓
Top SchoolStephane Zsoldos is an experimental particle physicist and scientist with 11 years of experience translating the physics of light into practical, data-driven solutions across quantum photonics, radiation, optics, and computational modeling. He led the design and construction of a £10M+ photosensor instrument for Hyper-Kamiokande, invented a cost-saving small-sensor architecture, and extended time-of-flight reconstruction into physics-informed deep learning that can render 3D event topology. At Exponent he applies quantum principles and photonics to commercial problems—including quantum-inspired modeling, radiation dosimetry, and explainable computer-vision systems for geoscience—while providing expert scientific support for legal and arbitration cases. He has a strong track record of publishing in top journals, keynote speaking for global neutrino collaborations, and supervising PhD students, combining hands-on detector build and DAQ design with scalable ML and HPC deployments. A less obvious strength is his ability to move techniques between domains—e.g., adapting neural-radiance-field ideas and raytracing from graphics into high-precision particle event reconstruction.
