Hi, I’m Samuel!
I’m doing a PhD at University of Cambridge in Computer Science. I enjoy working with computer architecture, computer graphics, and GPUs. My inspiration was video games, and I’ve worked on a few, but now I’m leaning more towards hardware and architecture.

All-Caps: My talk at CHERI Blossoms 2026
I got to give a short talk on my PhD work to close out the CHERI Blossoms 2026 conference! I was super excited to have the opportunity to present, and I think it went very well. This post serves as an archive of the video recording and the slide deck. Many thanks to my supervisor Simon W. Moore and collaborator Theo Markettos.
My first article!
My first article, “How Flexible is CXL’s Memory Protection?”, was just published in ACM Queue (it’s even on the front cover!) It discusses PCIe and CXL, their memory security model (and how it leaves something to be desired), and various flavors of capability which may be able to help. The article is available online here, and I plan to publish a copy here in the coming weeks to demo my pie-in-the-sky alternative typesetting language.
