About me: I’m Louie, an experimental particle physicist working at the Large Hadron Collider at CERN, in Geneva. On this page, you can find more information about my work, research interests and content such as the Particle Physics for Babies book. I’m passionate about communicating the exciting science of particle physics to the public. I am available to give talks and seminars for any level… just ask! You can find out more about me here.

Looking back on two years as ATLAS Exotics convener
It’s been three weeks since I concluded my term as Exotics convener of the ATLAS collaboration, a role which put me at the heart of the programme of searches for new particles and interactions at the LHC fo two years. It’s been an intense but fulfilling ride and I wanted to dedicate a post to…
How a tiny flash of light can set a field ablaze

Two lessons from ICHEP
Image: Me chairing a session on searches for particles beyond the Standard Model at ICHEP 2026. Photo by Giuliano Gustavino. About a month ago, I attended the “International Conference on High Energy Physics” (or ICHEP for short), which is the largest conference in the field and happens every two years. In contrast to Moriond, which…
