👋 Hi there!

I am a second-year PhD student at New York University, supervised by Prof. Eunsol Choi. Previously I worked with Yulia Tsvekov(Prof @UW).
 

🌋 Research Interests

My research interest lies in developing training and inference methods of machine learning. Recently, I’ve been thinking about:
  • real-world interactions between LLMs and human users, and aspects of evaluation.
  • when LLMs should be certain and when to be diverse? How to achieve it?
