I am Caihua Li, a PhD student at Yale University. I am a member of Yale Efficient Computing Lab and my advisor is Professor Lin Zhong. My research interest is building secure software system with novel programming language to preserve user's privacy. I received my B.S. from Peking University in 2018. Before that I worked as a research assistant in SOAR@PKU from 2017 to 2018, advised by Professor Chenren Xu. Beyond research, I enjoy teaching programming courses to high school students and popularizing cantonese cuisine to my friends.
