Jian Du

Jian Du is a research scientist at TikTok, leading the research and development efforts focused on integrating privacy-enhancing technologies into TikTok's products. For instance, Jian leads the development of PrivacyGo, an open-source project available on GitHub. Privacy Go aims to synergistically fuse PETs to address real-world privacy challenges, such as combining secure multi-party computation and differential privacy to enable privacy-preserving ad measurement and optimization of ad models, as well as privacy-preserving large language models. Prior to joining TikTok, Jian worked on PETs at Ant Financial and held a postdoctoral research position at Carnegie Mellon University.
