About me
Hello! My name is Zhepei (/dʒɜ:peɪ/) Wei, and I also go by Bruce. I'm a CS PhD student at the University of Virginia, advised by Prof. Yu Meng. Prior to this, I received my B.S. and M.S. degrees in Computer Science from Jilin University in 2019 and 2022. During the research journey, I was fortunate to have been advised by Prof. Hongning Wang and Prof. Yi Chang. I'm also a former research intern at Huawei Research.
For more information, please check my CV.

Research Interests
My recent research interest lies in the learning foundation of language model (LM) and its application in solving practical problems (e.g., information extraction, question answering, recommender system, etc.), with a focus on:
Retrieval-augmented LM
Textual Representation Learning
Trustworthy Language Generation and Reasoning
I also introduced the incentivized communication problem for contextual bandits (i.e., sequential decision-making agents) in federated environment (NeurIPS 2023, ICLR 2024).
