I'm a final-year PhD student at UIUC, working with Prof. Andrew Miller. At the moment, I am visiting Prof. Babis Papamanthou at Yale.
My research develops the cryptographic and systems foundations for verifiable and privacy-preserving identity infrastructure. I design protocols and proofs that make large-scale transparency and accountability possible without compromising privacy—both drawing on and advancing tools such as authenticated data structures, memory checking, and zero-knowledge proofs. My approach combines traditional applied cryptography with decentralized systems, using tools such as SNARKs and MPC to design protocols that are both rigorous and deployable. My work spans both theory and practice, from primitives—such as constraint-friendly map-to-elliptic-curve-group relations—to large-scale systems such as Parakeet (used by WhatsApp, awarded the IETF Applied Networking Research Prize), and CanDID, whose component DECO protocol is used by Chainlink Labs.
I am a two-time Facebook Fellowship finalist (2021, 2022).
