I am currently an Assistant Professor at Xi’an Jiaotong University. My research interests focus on data security and privacy issues in machine learning system. My vision is to protect the legitimate data rights and interests of every individual in the era of widespread artificial intelligence.

Each year, I have 1~2 openings for Master’s students, and undergraduate students are welcome to join our research.
If you are interested in these research topics, please feel free to contact me via email.
