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. I work on ML and NLP, with particular interests in LLM post-training. I am currently interested in data-centric offline methods for more effective offline learning and better warming-up for online learning.

I am applying to PhD programs for this round. Please feel free to reach out if you think I might be a good fit.
