Percy Liang: Advancing Artificial Intelligence and Foundation Models
In the rapidly evolving landscape of artificial intelligence, few figures bridge the gap between theoretical rigor and practical application as effectively as Percy Liang. A distinguished academic and researcher, Liang has dedicated his career to refining how machines understand human language and how large-scale models can be developed responsibly.
Academic Journey and Expertise
Following the completion of his doctorate, Liang gained industry experience through a postdoctoral position at Google. He subsequently transitioned to academia, joining the faculty at Stanford University. At Stanford, he balances his time between teaching and conducting cutting-edge research in several critical domains, including artificial intelligence, machine learning, statistical learning theory, and language modeling.
Liang is widely recognized for his contributions to semantic parsing—the process of mapping natural language to a formal meaning representation—as well as his work on weak and indirect supervision. His research also delves into the robustness and generalization of machine learning, ensuring that models perform reliably across diverse and unseen data.

Commitment to Reproducible Science
Beyond his theoretical work, Liang is a strong advocate for efficiency and reproducibility in scientific research. To support this goal, he co-developed CodaLab Worksheets, a specialized platform designed to help researchers manage and track computational experiments more effectively.
The Center for Research on Foundation Models (CRFM)
As the founding director of the Stanford Center for Research on Foundation Models (CRFM), Liang leads an interdisciplinary initiative housed within Stanford HAI (Human-Centered Artificial Intelligence). The center is dedicated to the holistic study of foundation models—large-scale AI models trained on vast amounts of data that can be adapted to a wide range of downstream tasks.
The CRFM focuses on three primary pillars:
- Development: Creating advanced architectural frameworks for AI.
- Evaluation: Establishing rigorous benchmarks to measure model performance.
- Governance: Addressing the social, technical, and policy implications of deploying powerful AI systems.
Under Liang's leadership, the CRFM has been instrumental in supporting the development of open-source large language models, promoting transparency and accessibility in the AI community.
Research Impact and Professional Recognition
Liang's scholarly influence is evident in his extensive list of peer-reviewed publications. His work frequently appears in the most prestigious AI and machine learning venues, including the Association for Computational Linguistics (ACL), the Conference on Empirical Methods in Natural Language Processing (EMNLP), the International Conference on Machine Learning (ICML), and the Conference on Learning Theory (COLT).
His contributions have earned him several prestigious accolades, reflecting his impact on both the theoretical foundations and the applied systems of natural language understanding.
