Zhengzhong Jin is an assistant professor in the Khoury College of Computer Sciences at Northeastern University, based in Boston. He is a member of the Cybersecurity and Privacy Institute.

As a researcher and teacher, Jin’s focus is on cryptography, which he grew passionate about during his undergraduate courses in theoretical computer science. In particular, he has worked to develop a proof system that enables clients to delegate heavy computation to an untrusted server and still ensure that the computation is done correctly. These cryptographic proofs can be applied in many practical areas, including blockchain and cryptocurrency technologies.

Before joining Khoury College in 2024, Jin was a postdoctoral associate at the Massachusetts Institute of Technology and a winner of multiple best paper awards at conferences such as EUROCRYPT and ACNS. He has been a member of the program committee for multiple conferences, including TCC 2023, PKC 2024, and CRYPTO 2024.

Jin also plans to involve himself in quantum computing and machine learning research in the future. He believes that those areas may present challenges and exciting possibilities for cryptography.
