Summary
🤩
RockstarJiefeng Li is a visiting research fellow in London with a PhD in Electrical and Electronics Engineering from Cambridge and three years of focused postdoctoral research experience in microwave and millimetre-wave technologies, especially liquid-crystal–based tunable devices for beam steering and 5G/automotive radar applications. He combines deep academic expertise—leading projects from design through micro/nanofabrication and characterisation—with practical software and security experience from roles at Barclays and blockchain smart-contract development on Sui. Equally at home in labs and code, he has built firmware-level proofs of concept, implemented SAST/pen-testing demos, and contributed backend Move modules for NFTs and DEX functionality. A classically trained concert pianist with a proven record as a popular content creator, he brings uncommon communication and teaching skills that help translate complex research into usable systems and outreach.
