Christopher Finch

Infrastructure Engineer & Medical Physicist

Building tools at the intersection of healthcare, industrial automation, and AI. 20+ years spanning the NHS, medical physics, and proton therapy infrastructure.

About

I'm an infrastructure engineer at IBA, supporting proton therapy systems across 20+ sites worldwide. I manage the compute, networking, and data infrastructure that keeps particle accelerators treating cancer patients.

Outside work, I build open source tools for infrastructure automation, industrial control, and AI agent orchestration.

My background is in medical physics (MSc Leeds, MPhys Manchester) with deep experience in healthcare IT, radiation dosimetry, and hospital networking. Currently exploring formal methods with Lean 4 and category theory.

Projects
