I finished my PhD in Nuclear Engineering in 2025 — as the youngest graduate in my program. I've spent the past several years working at the intersection of physics, engineering, and machine learning, and teaching is what I keep coming back to.

When students I'd helped with AFOQT prep, physics, and AI/ML asked me to build a community where they could study together and ask questions freely, the answer was obvious. FissionLab exists because you asked for it — and because rigorous STEM education should be accessible to people who are serious about it.

Dr. Preston holds a PhD in Nuclear Engineering and has guided students to significant improvements across AFOQT subtests, physics courses, and AI/ML foundations. His approach is built on deep subject mastery, not shortcuts.
