Research Interests: I have a broad interest in Theoretical Computer Science. Currently, I am working on Cryptography and Coding Theory. I am a fourth year Ph.D. student at Johns Hopkins University, fortunately co-advised by Abhishek Jain and Xin Li. Previously, I received my bachelor's degree in Information and Computing Science in School of Mathematical Sciences at Fudan University, and was fortunately advised by Prof. Yunlei Zhao. My favorite paper is C.E. Shannon's A Mathematical Theory of Communication. Contact: zjin12 (AT) jhu (DOT) edu |
