Bio

Wu Yonghui is a Chinese-American computer scientist. He is the head of foundational research at ByteDance Seed, a position he has held since February 2025, and is based in San Jose, California, where he reports directly to ByteDance chief executive Liang Rubo. He spent seventeen years at Google before joining ByteDance, ultimately as a Google Fellow and vice president of research at Google DeepMind. At ByteDance, his work has anchored the Doubao 2.0 large-language-model release and the Seedance 2.0 video-generation model.

Education

Wu completed his undergraduate degree at Nanjing University. He moved to the United States for graduate study, completing a Master of Science in statistics and a Doctor of Philosophy in computer science at the University of California, Riverside, with the doctorate completed around 2008.

Career

Wu joined Google as a software engineer in 2008 and rose through the company's research and engineering organizations over the next seventeen years. He was an early member of Google Brain from 2014 onward, contributing to machine learning, genomics, and natural-language-understanding research. He was promoted to Google Fellow in September 2023, the company's most senior individual-contributor research title, and reached the role of vice president of research at Google DeepMind before his departure.

He left Google to join ByteDance Seed in February 2025 as head of foundational research, with reporting directly to ByteDance CEO Liang Rubo. The recruitment was framed in industry coverage as ByteDance's response to the January 2025 DeepSeek-R1 release, which had reframed Chinese-lab competitive position in the global LLM industry, and as a structural change to the company's earlier in-house Seed model team led by Zhu Wenjia. Zhu has subsequently led Seed's model-applications work and now reports to Wu rather than to Liang Rubo directly.

The first major output of Wu's tenure has been the Doubao 2.0 large language model, characterized in industry coverage as the most significant outcome of his first year at the company, and the Seedance 2.0 video-generation model.

Notable contributions

Wu's published record from the Google period covers machine learning, natural language understanding, and genomics, with broad citation across the Google Brain and DeepMind research portfolios. Specific paper-by-paper contributions are not consolidated in publicly accessible summaries.

• ByteDance Seed head of foundational research (February 2025 onward). Leadership of the company's foundational LLM research.
• Doubao 2.0 (2026). The model release framed as the most significant outcome of his first year at ByteDance.
• Seedance 2.0 video-generation model.

Affiliations

• Nanjing University: Bachelor's student.
• University of California, Riverside: Master's student in statistics; Doctoral student in computer science, completed approximately 2008.
• Google: Software Engineer, then Google Brain researcher, then Google Fellow (September 2023), then Vice President of Research, Google DeepMind, 2008 to 2025.
• ByteDance Seed: Head of Foundational Research, February 2025 to present.

Position in the field

As of May 2026, Wu is the most senior Western-domiciled Chinese-American AI researcher to have moved from a US frontier lab to a Chinese frontier lab during the post-DeepSeek period, and his February 2025 hire is the most-cited example of the broader pattern in industry coverage. The reporting line to chief executive Liang Rubo, the San Jose base, and the Doubao 2.0 and Seedance 2.0 releases collectively position him as one of the principal Chinese frontier-lab research leaders.

The structural change at ByteDance Seed associated with Wu's arrival has been a re-organization of the lab into a foundational-research unit (Wu's domain) and a model-applications unit (under Zhu Wenjia), a separation that mirrors the structure at peer Chinese frontier labs. Industry coverage has characterized the move as a deliberate import of the US-frontier-lab research-management model into a Chinese-domiciled organization.
