Hello! Welcome to my homepage. I am Liu Junhao (刘俊豪), a PhD student in the Programming Language Lab at Peking University, advised with Prof. Zhang Xin .
My research interests lie in the field of Explainable Artificial Intelligence (XAI), which focuses on developing machine learning and deep learning techniques that are transparent, interpretable, and understandable to humans. I am particularly interested in creating XAI methods that enhance human understanding, foster trust, and support decision-making in complex AI systems.
I was previously active in competitive programming, having earned several gold medals in the ICPC Asia-East Continental Final and Regional Contests. I also won a gold medal in the National Olympiad in Informatics in 2017. Additionally, I am a co-founder of the PKU Student Algorithm Association.
In my spare time, I enjoy sim racing and am an fan of the Formula 1 racing series—especially the Scuderia Ferrari team (tifosi). I'm hoping to see them win the championship in 20252026.
The most important lesson learned in programming language lab is to learn more languages. 除咗英文同普通話，我亦懂得啲粵語，咁我哋都可以用粵語進行學術交流。 日本語でもいい。
