Sudip Roy

Sudip Roy is a computer scientist whose work centers on the systems that train and serve large machine-learning models. He holds a B.Tech from IIT Kharagpur and finished a PhD at Cornell in 2014; a paper he co-authored there on entangled queries won the SIGMOD 2011 best paper award. At Google Brain he worked on systems research and contributed to TensorFlow Extended and Pathways, and the Pathways paper won an MLSys Outstanding Paper Award in 2022. After rising from engineering manager to senior director of inference at Cohere between 2021 and 2025, he co-founded Adaption Labs with Sara Hooker in 2025, and the company raised a $50 million seed round in 2026. He is co-founder and chief technology officer of Adaption.

Timeline

  1. 2011

    A SIGMOD best paper

    He is a co-author, with Cornell colleagues including Johannes Gehrke, of "Entangled queries: enabling declarative data-driven coordination", which wins the SIGMOD 2011 Best Paper Award.

  2. By 2014

    A Cornell PhD

    He holds a B.Tech in computer science and engineering from the Indian Institute of Technology Kharagpur. He finishes a PhD in computer science at Cornell under Johannes Gehrke in 2014.

  3. By 2021

    Systems work at Google Brain

    At Google Brain, he works on systems research and large-scale data management, and contributes to infrastructure projects including TensorFlow Extended and Pathways. In 2021, he is a co-author of an MLSys paper that learns a performance model for Tensor Processing Units from a corpus of tensor computation graph programs.

  4. 2022

    Pathways at MLSys 2022

    He is a co-author of Pathways: Asynchronous Distributed Dataflow for ML, which presents an orchestration layer for accelerators designed to enable exploration of new systems and ML research ideas. The paper receives an Outstanding Paper Award at MLSys 2022.

  5. 2021–2025

    Engineering leadership at Cohere

    He joins Cohere as an engineering manager in November 2021 and becomes director of engineering in June 2023. From January 2025, he is senior director of inference, leading work on inference infrastructure and fine-tuning systems.

  6. October 2025

    Co-founding Adaption Labs

    In October 2025, he joins Sara Hooker, the former head of Cohere Labs, in launching Adaption Labs. The startup aims to build efficient AI that can adapt and continuously learn.

  7. February 2026

    A $50 million seed round

    Adaption Labs raises $50 million in seed funding in February 2026. Emergence Capital Partners leads the round, with Mozilla Ventures among the participants.

  8. As of October 2026

    Chief technology officer of Adaption

    He is co-founder and chief technology officer of Adaption, a San Francisco company building AI that adapts and keeps learning. In May 2026, Adaption launches AutoScientist, an automated fine-tuning system that the company says raised win rates from 48% to 64% against configurations its own AI researchers picked.

From the biography and OpenAlex affiliations (the years of papers that list the organization), so some years are approximate.

  1. Google alumni have founded or led 133 other organizations, more than any other AI labIncludes Sudip Roy. We estimate that alumni of 17 major AI labs went on to found or lead 350 other organizations, including 226 they founded, and we trace 472 career moves directly between 23 labs since 2010.
  2. Of 943 people shaping AI who worked at Google, 446 work there nowIncludes Sudip Roy. Our estimates of where the 943 people shaping AI who worked at Google and Google DeepMind work now: 446 at Google and 452 across 278 other organizations.
  3. 11% of AI doctorate holders from 2010 to 2016 founded or led a company or lab by 10 years after graduationIncludes Sudip Roy. We estimate how often AI doctorate holders founded or led a company or lab by 10 years after graduation, how waiting times compare between founders and top jobs, and which universities trained the most.
  4. Google had the most people shaping AI every year from 2014 to 2025Includes Google. Our estimates of which organizations employed the most people shaping AI each year from 1955 to 2025, tracing the shift from university labs to companies.
