I am a third-year PhD student in programming languages at the University of Edinburgh, supervised by Dr. Sam Lindley. I am interested in types and effects.
I received my bachelor’s degree from Peking University, where I worked on program calculation and bidirectional programs supervised by Prof. Zhenjiang Hu. I did a research internship with Prof. Tom Schrijvers working on algebraic and scoped effects in 2021.
