{"id":"chenxi-liu","title":"Chenxi Liu","content":"**Chenxi Liu** is a research scientist specializing in artificial intelligence, computer vision, and deep learning. He is a member of [Meta's Superintelligence Labs](https://iq.wiki/wiki/meta-superintelligence-team) and previously worked at Google DeepMind, where he was a core contributor to the Gemini family of multimodal models. [\\[1\\]](#cite-id-guBjJ7whtw) [\\[2\\]](#cite-id-Xdn26DCTyA)\n\n## Education\n\nLiu completed his undergraduate studies at Tsinghua University, where he earned a bachelor's degree in automation. He continued his education in the United States, obtaining a master's degree in statistics from the University of California, Los Angeles (UCLA). Liu then pursued his doctoral studies at Johns Hopkins University, where he was advised by Bloomberg Distinguished Professor Alan Yuille. He graduated with a Doctor of Philosophy (PhD) in computer science, with his research focusing on computer vision and deep learning. [\\[3\\]](#cite-id-477dDmsy4k) [\\[4\\]](#cite-id-aIzprVvgvp) [\\[7\\]](#cite-id-7gyaBxojI3)\n\n## Career\n\nAfter completing his PhD, Liu began his professional career as a senior researcher at Waymo, the autonomous driving technology company. He later joined Google DeepMind as a staff research scientist. At DeepMind, he was part of the team responsible for the post-training of the Gemini series of large language models and is listed as a core contributor on the technical reports for Gemini, Gemini 1.5, and Gemini 2.5.\n\n$$widget0 [YOUTUBE@VID](https://youtube.com/watch?v=pz-uELduTLI)$$\n\nIn 2025, Liu joined Meta as a research scientist in the company's newly established [Superintelligence Labs](https://iq.wiki/wiki/meta-superintelligence-team). His recruitment was part of a broader initiative by Meta to assemble a team of prominent researchers from organizations like OpenAI and DeepMind to focus on the development of artificial general intelligence (AGI).

He has published numerous papers at major AI conferences such as the Conference on Computer Vision and Pattern Recognition (CVPR), the European Conference on Computer Vision (ECCV), and the International Conference on Learning Representations (ICLR).\n\nHis work at Google DeepMind involved significant contributions to the Gemini project, a family of highly capable multimodal models. Before his work on large language models, Liu's research focused on automatically discovering efficient neural network architectures. His work on \"Progressive Neural Architecture Search\" (PNAS) introduced a method for learning the structure of a convolutional network that was more efficient than previous approaches. Another notable work, \"Auto-DeepLab,\" presented a hierarchical neural architecture search algorithm for semantic image segmentation. [\\[1\\]](#cite-id-guBjJ7whtw) [\\[8\\]](#cite-id-how5pXVbHV)\n\nA selection of his major works includes:\n\n* **Gemini: a family of highly capable multimodal models** (2023): As a core contributor, Liu was part of the team that developed Google's foundational multimodal model.\n* **Auto-DeepLab: Hierarchical Neural Architecture Search for Semantic Image Segmentation** (CVPR, 2019): This paper proposed a method for searching for mobile-sized segmentation models that are computationally efficient.\n* **Progressive Neural Architecture Search** (ECCV, 2018): This work introduced a novel, search-based method for identifying high-performance convolutional neural network architectures on large-scale datasets like ImageNet.\n* **Recurrent Multimodal Interaction for Referring Image Segmentation** (ICCV, 2017): This paper addressed the task of segmenting an object in an image specified by a natural language expression.\n* **Rent3D: Floor-Plan Priors for Monocular Layout Estimation** (CVPR, 2015): An early work that utilized floor-plan priors to estimate 3D room layouts from a single image.\n\nThis list represents a small portion of his extensive publication record. [\\[1\\]](#cite-id-guBjJ7whtw) [\\[8\\]](#cite-id-how5pXVbHV)\n\n## Awards and Recognition\n\nIn 2019, Liu was named a Google AI Fellow, an award created to recognize and support outstanding graduate students conducting exceptional research in computer science and related fields. He was one of 54 students selected for the fellowship, which provided two years of paid tuition and fees. At the time of the award, Liu stated his research goal was \"to let the machines spontaneously and efficiently discover architectures that best facilitate various kinds of visual intelligence tasks.\" [\\[4\\]](#cite-id-aIzprVvgvp)","summary":"Chenxi Liu, an AI research scientist at Meta Superintelligence Labs and a Johns Hopkins Ph.D., specializes in computer vision and vision-language models, having previously worked on Google DeepMind's Gemini models.","images":[{"id":"QmYMuiCvfMJNHdb7pFR9FA6ZBsTMcdKPr5o3rpJe1avsu5","type":"image/jpeg, image/png"}],"categories":[{"id":"people","title":"people"}],"tags":[{"id":"AI"},{"id":"Developers"}],"media":[{"id":"QmXVRsJyD5aPLqCSQkBQpdTbgpHaNCDVNT6LqNiSdY1r2H","name":"1517031925036.jpeg","caption":"","thumbnail":"QmXVRsJyD5aPLqCSQkBQpdTbgpHaNCDVNT6LqNiSdY1r2H","source":"IPFS_IMG"},{"id":"https://www.youtube.com/watch?v=pz-uELduTLI","name":"pz-uELduTLI","caption":"","thumbnail":"https://www.youtube.com/watch?v=pz-uELduTLI","source":"YOUTUBE"}],"metadata":[{"id":"references","value":"[{\"id\":\"guBjJ7whtw\",\"url\":\"https://chenxi116.github.io/\",\"description\":\"Chenxi Liu's personal website\",\"timestamp\":1756309255597},{\"id\":\"Xdn26DCTyA\",\"url\":\"https://medium.com/g-able/unpacking-metas-superintelligence-team-a-deep-dive-into-their-ambitious-ai-play-99cc821cffb7\",\"description\":\"Analysis of Meta's Superintelligence team\",\"timestamp\":1756309255597},{\"id\":\"477dDmsy4k\",\"url\":\"https://eu.36kr.com/en/p/3388366874230921\",\"description\":\"Profile of Meta's AGI team members\",\"timestamp\":1756309255597},{\"id\":\"aIzprVvgvp\",\"url\":\"https://ccvl.jhu.edu/news/2019/chenxi-fellowship/\",\"description\":\"Johns Hopkins University announcement\",\"timestamp\":1756309255597},{\"id\":\"QzwESpz4tc\",\"url\":\"https://x.com/chenxi116\",\"description\":\"Chenxi Liu's professional profile on X\",\"timestamp\":1756309255597},{\"id\":\"6Ao1lL6PlE\",\"url\":\"https://www.ainvest.com/news/meta-super-smart-lab-sparks-tech-buzz-global-talent-ai-ambitions-2507/\",\"description\":\"News report on Meta's Superintelligence Lab\",\"timestamp\":1756309255597},{\"id\":\"7gyaBxojI3\",\"description\":\"LinkedIn: Chenxi Liu\",\"timestamp\":1756309756708,\"url\":\"https://www.linkedin.com/in/chenxi116/\"},{\"id\":\"how5pXVbHV\",\"description\":\"Google Scholar: Chenxi Liu\",\"timestamp\":1756309890123,\"url\":\"https://scholar.google.com/citations?user=qvRsU00AAAAJ\"}]"},{"id":"linkedin_profile","value":"https://www.linkedin.com/in/chenxi116/"},{"id":"website","value":"https://chenxi116.github.io/"},{"id":"email_url","value":"mailto:cxliu@ucla.edu"},{"id":"github_profile","value":"https://github.com/chenxi116"},{"id":"twitter_profile","value":"https://x.com/chenxi116"},{"id":"youtube_profile","value":"https://www.youtube.com/@chenxiliu7100/"},{"id":"previous_cid","value":"\"https://ipfs.everipedia.org/ipfs/QmWDq1LBJAQZWnCVsiML86T2hyGhyamjCN7CC7qJB8iZ2j\""},{"id":"commit-message","value":"\"Republishing Chenxi Liu wiki\""},{"id":"previous_cid","value":"QmWDq1LBJAQZWnCVsiML86T2hyGhyamjCN7CC7qJB8iZ2j"}],"events":[{"id":"a9b23621-97fe-442b-b6fd-156689f74fe9","date":"2019-09","title":"Named Google AI Fellow","type":"DEFAULT","description":"Selected as one of 54 students for the 2019 Google AI Fellowship while a PhD student at Johns Hopkins University, recognizing his research in artificial intelligence.","multiDateStart":null,"multiDateEnd":null},{"id":"028cebed-1b9a-4762-abae-7660e01aabcc","date":"2020-08","title":"Earned Ph.D. from Johns Hopkins","type":"DEFAULT","description":"Completed his Ph.D. in Computer Science from Johns Hopkins University, where he was advised by Alan Yuille.
