Greetings and welcome to my homepage


I received my Ph.D. degree in Computer Science and Technology from Tsinghua-Berkeley Shenzhen Institute (TBSI), Tsinghua Shenzhen International Graduate School (SIGS), Tsinghua University in 2023, advised by Professor Yong Jiang and Professor Shu-Tao Xia. Before that, I received my B.S. degree with honors in Mathematics and Applied Mathematics from Yangming Innovation Class, Ningbo University in 2018, advised by Professor Lifeng Xi.

At the beginning of my Ph.D. journey, I studied tree-based methods for their interpretability and good theoretical properties. Currently, my research mainly focuses on Trustworthy ML, especially backdoor learning, adversarial learning, data privacy, and copyright protection in deep learning. My long-term goal is to make DL-based systems more robust and secure during their full life cycle. Most recently, I focus more on the security issues of large foundation models (e.g., DALL-E and GPT-4). I always chase for simple yet effective methods with deep insights or even theoretical supports. My research is supported by the Tsinghua ‘Future Scholar’ Ph.D. Fellowship.

Currently, I am working with Professor Bo Li at UIUC as a visiting Ph.D. student (online), started from January 2022. I was a research intern at Ant Security Lab (2021, 2022), working with Dr. Haiqin Weng and Dr. Tao Wei; a research intern at Tencent AI Lab (2019, 2020), working with Dr. Baoyuan Wu and Dr. Zhifeng Li (supported by the Tencent Rhino-bird Elite Training Program); an intern at Wukong Investment (2018), working with Dr. Xinji Liu on ML-based high-frequency trading.

I am always willing to work together on interesting projects. Feel free to drop me an email if you have any ideas or suitable opportunities to discuss!
