HELLO! I'M YANSONG FENG ▼
▶ ABOUT ME:
I am a Ph.D. student advised by Yanbin Pan and an AI4Crypto research intern at MiniMax. My research focuses on algorithmic number theory and combinatorics, with applications to cryptography and theoretical computer science. Recently, I am also interested in AI for security and AI-assisted formal verification.
I expect to graduate in 2027 and am seeking full-time opportunities in industry or as a postdoctoral researcher. Please feel free to contact me!
