Chenghao Yang is a Senior Applied Scientist with a decade of experience specializing in NLP, semantics, knowledge graphs, and information retrieval, currently building Copilot at Microsoft. He holds a PhD in progress from the University of Chicago and has blended academic rigor with industry impact through roles at Google, AWS, IBM and research positions across JHU, Columbia and Tsinghua. His work spans large-language-model research for long-context understanding (Random-Access Transformer) and practical engineering for code-generation systems like AWS CodeWhisperer. Chenghao has published and presented at top venues (TACL, ACL, NAACL) and contributed to robustness and interpretability benchmarks in production-relevant settings. Comfortable moving between pre-training research and deployed model evaluation, he combines deep semantic curiosity with hands-on product delivery. A recurring theme in his career is bridging theoretical insights into scalable systems that improve real-world language understanding.
