Dung Bui — Cryptography

Abstract

From summer 2026, I am a postdoctoral researcher at Northwestern University, working with Xiao Wang. My research focuses on cryptography, including secure multiparty computation, zero-knowledge proofs, and post-quantum cryptography. I am particularly interested in bridging theory and practice: designing protocols that are both provably secure and efficient enough for real-world use.

I completed my PhD at IRIF, Université Paris Cité, under the supervision of Geoffroy Couteau. Before that, I obtained my Master's degree (2019–2021) in Cryptology and Information Security through the Cryptis program at Université de Limoges.
