# Bio

I am a third-year PhD student at Duke University, advised by Bhuwan Dhingra (opens new window) and previously Sam Wiseman (opens new window). I am a member of DukeNLP (opens new window). 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 (opens new window) working with Yangfeng Ji (opens new window). I've also spent time at Google DeepMind (opens new window), Microsoft Advertising, and Microsoft Research (Beijing (opens new window) and Redmond (opens new window)).

I was lucky to have the opportunity 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.
