Yu Xia is an algorithm developer with seven years of experience blending academic rigor and production-grade systems work across databases, distributed systems, cryptography, blockchain, and AI. Based in Cambridge, MA, he holds a PhD from MIT and a strong CS foundation from Tsinghua, and spent six years as an MIT research assistant before moving to Hudson River Trading. He has hands-on blockchain experience—doubling Diem throughput during a Facebook Novi internship and contributing core decoupled-execution components to the Diem repo, including efficient buffer management and consensus signing logic. Yu combines theory and practice, designing data structures and proofs-aware systems while shipping robust implementations and tests. He’s comfortable in both research labs and high-frequency trading environments, with internships at Microsoft Research and NTT Research underscoring a breadth of collaboration. Colleagues describe him as a researcher-engineer who turns deep theoretical insight into performant, production-ready code.
