I am Kai Chen, a third-year PhD student in Computer Science at the University of Virginia, advised by Dr. Tianhao Wang. I obtained my Bachelorโs degree in Mathematics and Applied Mathematics at Zhejiang University, and earned a double major in Finance. I received my Masterโs degree in Statistics with Data Science from the University of Edinburgh. Before starting my PhD studies, I spent about one and a half years working at ByteDance as a Data Analyst. In 2026, I was a Student Researcher at Google Research.
My research interests include differential privacy, generative AI, and AI security. I actively welcome any collaborators. If you are interested in differential privacy and its applications in data generation, please donโt hesitate to contact me.
