Research, music, and systems
Alongside doctoral research in quantum materials, Chris builds websites, publishing tools, and educational systems through QuantaLumin and TutorLumin.
His work brings together scientific research, performance, and practical software, treating each as a discipline of structure, timing, and attention to detail.
Outside research and music, Brazilian Jiu Jitsu is a steady part of that practice: long-term training, measured progress, and repetition refined over time.
