Bio

I am a final-year PhD student at Duke University, advised by Bhuwan Dhingra and previously Sam Wiseman. I am a member of DukeNLP. My research investigates how LLMs continually learn, explore, reason, and plan in dynamic environments.

I did my master's work at the University of Virginia, where I was a member of the ILP Lab working with Yangfeng Ji. I've also spent time at Google Research, Google DeepMind, Microsoft Advertising, and Microsoft Research (Beijing and Redmond).

Misc

I am originally from Quanzhou, China. It was one of the world's largest and most cosmopolitan seaports and now a World Heritage Site. (Interestingly, UVA is also a World Heritage Site.)
I started playing the violin when I was seven.
I enjoy photography and traveling.
