Bio

I am a fourth-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 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 DeepMind, Microsoft Advertising, and Microsoft Research (Beijing and Redmond).

I was lucky to have great mentors and be involved in research during my undergrad study. If you're a Duke undergrad and feel like I can be of some help to your research career, feel free to email me!
