Hi there, I am Joshua 👋

Staff Physicist @ CERN

FCC

FCC

I develop simulation and reconstruction software for the Future Circular Collider (FCC) — CERN's proposed 91 km successor to the LHC, designed to probe the Higgs boson and open questions in fundamental physics with unprecedented precision.

Previously, I led the development of the fast simulation software of the ATLAS Experiment, now used extensively in physics analyses and large-scale Monte Carlo production.

My interests span detector simulation, reconstruction, scientific computing, and high-performance software for particle physics. Most of my work is in C++ and Python, alongside the broader high-energy physics software ecosystem.

Feel free to reach out if you'd like to discuss physics, software, open-source development, or potential collaborations.
