👤
Senior🎓
Top SchoolRuiyi Zhang is a Ph.D. student at CISPA focused on microarchitectural and TEE security, with eight years of hands-on experience uncovering CPU vulnerabilities and building side-channel attacks and defenses such as #umwait and CacheWarp. He combines deep academic research with practical industry exposure, including a recent research internship at Google and multiple roles at PeckShield where he led fuzzing, reverse engineering, and vulnerability detection for blockchain smart contracts and WASM. Ruiyi’s work spans low-level CPU microarchitecture to applied security tooling, and he has contributed to public audit reports and publications that bridge research and real-world impact. Based in Saarbrücken, he brings a rare mix of offensive security expertise and systems-level research rigor that informs both novel attacks and mitigations.
