| Bill Yuchen Lin is a researcher at xAI and an Affiliate Assistant Professor at the University of Washington (UW). His research centers on aligning large language models (LLMs), training AI agents, reasoning, and multi-modal LLMs, with a focus on post-training, evaluation, reward modeling, and synthetic data generation. He also aims to deepen the core understanding of language models and explore their limitations, with experience in enhancing the safety, generalization, robustness, and efficiency of LLMs. Lin has received several honors, including the Best Paper Award at CoRL 2024's LangRob Workshop, the Best Paper Award Runner-up at The Web Conference 2020, the Best Paper Award at TrustNLP 2021, and recognition as an AI Rising Star by Baidu Scholar. He serves as a Senior Area Chair for the Association for Computational Linguistics (ACL) and an Area Chair for the International Conference on Learning Representations (ICLR). Previously, he was a research scientist at the Allen Institute for AI (Ai2), where he worked with Prof. Yejin Choi. Lin has also interned at Meta FAIR Lab, Google AI, Facebook AI Research (FAIR), and Microsoft Research Asia. Lin earned his Ph.D. from the University of Southern California in 2022. He completed his bachelorβs degree in the IEEE Honor Class at Shanghai Jiao Tong University (2014β2018), where he received the Best Thesis Award. |
