About
Hello! I’m a second-year Ph.D. student at the School of Computer Science, Beijing Institute of Technology, supervised by Prof. Rong-Hua Li. Before starting my Ph.D., I obtained a BSc degree in the School of Mathematics from Beijing Institute of Technology. My current research focuses on spectral graph algorithms and sampling algorithms. I’m also broadly interested in combinatorics and theoretical computer science.
Always open to new collaborations and chats՞˶･֊･˶՞
Contact me through e-mail (yc.yang@bit.edu.cn) or WeChat (Berserker_60) if you are interested.
