Haojin Wang

Heyyy, welcome to my homepage 😊

I am a Master's student in Computer Science at University of Illinois Urbana-Champaign (UIUC). I work on ML and NLP, with particular interests in LLM post-training (test-time approaches: collaborative decoding time adapatation; training-time approaches: data-centric offline/online methods).

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