Percy Liang

Stanford AI professor affiliated with HAI — known for creating HELM (Holistic Evaluation of Language Models), the Center for Research on Foundation Models (CRFM), and research on NLP, program synthesis, and AI transparency and evaluation.

Created the standard for evaluating language models at scale — HELM's comprehensive evaluation of dozens of LLMs across hundreds of tasks established the benchmark methodology for the AI evaluation field, and CRFM at Stanford became the institutional home for foundation model research.
