About Me

I am a third-year Ph.D. student in the School of Computer Science at Carnegie Mellon University (CMU), advised by Sarah Scheffler. I am a member of CyLab, the security and privacy institute at CMU. Before studying at CMU, I obtained my bachelor’s degree from Tsinghua University. I went on to earn master’s degrees from the University of Pennsylvania (M.S. in Computer and Information Technology) and the University of California, Berkeley (LL.M. in Technology and Law).
