About Me Icon

Hey 👋 I’m Luke, a PhD student at King’s College London, studying in the CDT for Safe & Trusted AI, under the supervision of Dr Jie M. Zhang.

With over 8 years of industry experience in software engineering and technical leadership roles, I’m passionate about harnessing artificial intelligence to transform software engineering - bridging real‑world expertise with cutting‑edge research to build systems that are safe, robust, innovative, and genuinely useful.

If you’re a researcher or practitioner working in these areas and are interested in collaborating, I’d love to connect — reach out via email 📨.
