About me

Hi, I'm Yikang, a second-year graduate student of computational linguistics at Shanghai Jiao Tong University (SJTU). I am currently advised by Hai Hu, and work closely with Rui Wang. Before that, I received my B.A. in English and Minor B.Eng. in CS from Huazhong University of Science and Technology (HUST).

For now, I am trying to understand the behavior of language models by analyzing how they process human-understandable linguistic features.

My story with language started with The Lord of the Rings, which I was fascinated by as a child. Then I came to know that J.R.R Tolkien was a philologist, which inspired me to learn language. During my first year as an undergraduate, I realized that language can go beyond literature and philology. One can look into language by building computational models, from perspectives of science and engineering. Thus I started a minor program in computer science, and later I decided to pursue a master's degree in computational linguistics.

For my daily hobbies, I like to play the violin and listen to classical music, especially symphonies and violin concerto. I was once a violin player in the student ochestra of HUST, performing a New Year Concert in the magnificant Qintai Concert Hall in Wuhan!
