Haojin Wang

Heyyy, welcome to my homepage 😊

I am a Master's student in Computer Science at University of Illinois Urbana-Champaign (UIUC), working with Professor Hao Peng. My research focuses on language models, with particular interests in: i) (collaborative) inference-time algorithms; ii) interpretability within/across model(s); iii) data-centric methods in language model(s) post-training. I am currently working on self-distillation.

I am applying to PhD programs in NLP for Fall 2027. Please feel free to reach out if you think I might be a good fit. I am also open to collaborations related to these research areas.
