Wang Haifeng

Overview

Wang Haifeng is the chief technology officer of Baidu ^[1]. His work has centred on machine translation (MT), natural language processing (NLP) and search engines, and he has held senior positions in both academia and industry — a combination the Association for Computational Linguistics (ACL) named explicitly when it made him a Fellow ^[2].

Education and early research

Wang holds a doctorate in computer science from Harbin Institute of Technology ^[5]. Before joining Baidu he was chief research scientist at the research and development centre of Toshiba ^[5], an industrial research post in which a senior scientist leads a group's research agenda rather than a single product line.

Career at Baidu

He joined Baidu in January 2010 ^[4] and moved up through a series of roles: senior scientist, chief scientist of basic technology, vice president, and senior vice president ^[4]. He is now the company's chief technology officer ^[1]. The progression traces a common path in large technology firms, from a research position toward responsibility for a whole company's technical direction.

The ERNIE models

Baidu's ERNIE family are foundation models: large neural networks pretrained on broad data and then adapted to many downstream tasks rather than trained for one narrow job. Wang has spoken publicly for the family at its releases. At the ERNIE 4.0 launch in October 2023 he said the model's overall performance had improved by almost 30% since beta testing began in September ^[1]. He is also the first-listed author of the ERNIE 5.0 Technical Report, posted to arXiv on 4 February 2026 and credited to Baidu's ERNIE Team ^[3]. A technical report of this kind is the document in which a model team sets out how a system was designed, trained and evaluated, so that outside researchers can follow and check the work; being listed first among the authors marks the lead role on that document ^[3].

Recognition

Wang was named an ACL Fellow in 2016 "for significant contributions to MT, NLP and search engines in both academia and industry, and to the growth of the ACL in Asia" ^[2]. Fellowship is the honour the association gives researchers with a sustained record of important work in computational linguistics. He was also named an IEEE Fellow in the 2021 list ^[6].

His record includes service to the research community as well as research: he was the founding chair of the ACL's Asia-Pacific chapter (AACL) from July 2018 ^[4]. The chapter was set up to give researchers in the region a forum of their own within the parent association, which had historically been centred on North America and Europe.

His work has been recognised with a second-class National Science and Technology Progress Award and four first-class provincial or ministerial science and technology progress awards ^[4].

Why his career is studied

Wang's profile is unusual in combining three things at once: academic honours from the main international bodies in his field, a research background outside China's own internet companies, and executive responsibility for the technical direction of one of the largest AI companies. For readers trying to understand how research fields turn into products, he is a case where the same person appears in the citation of a scholarly society and in the launch materials of a commercial model — the two records, academic and industrial, describing the same body of work ^[2][3].
