Researcher

Siva Reddy

Siva Reddy is a computer scientist who develops AI methods for language understanding and reasoning. He pursued a PhD at the University of Edinburgh with a Google PhD Fellowship in 2015, completed a postdoctoral role at Stanford's NLP Group by September 2019, and by January 2020 was a joint faculty member at McGill and a Facebook CIFAR AI Chair at Mila. His work includes CoQA, StereoSet, MaRVL, StarCoder, and LLM2Vec, spanning conversational question answering, stereotype-bias measurement, cross-cultural visual reasoning, code models, and text embeddings. He received the CS-CAN Outstanding Early Career Computer Science Researcher Award in 2025 and a Sloan Research Fellowship in 2026. As of October 2026, he is an AI Scientist at Mistral and an Associate Professor on leave at McGill, a Canada CIFAR AI Chair, and a core academic member of Mila.

Timeline

  1. 2015

    A Google PhD Fellowship

    While pursuing his PhD at the University of Edinburgh, he receives support from the Google PhD Fellowship in 2015.

  2. By 2019

    Postdoctoral work at Stanford

    At Stanford University's NLP Group, he works as a postdoctoral researcher until September 2019.

  3. 2019

    CoQA for conversational question answering

    He coauthors CoQA in 2019, a dataset with 127,000 questions and answers from 8,000 conversations about text passages.

  4. By January 2020

    Joint faculty member at McGill

    By January 2020, he is a joint faculty member in McGill’s School of Computer Science and Department of Linguistics and holds a Facebook CIFAR AI Chair at Mila. His research builds symbolic and deep-learning models for language understanding, including question answering and conversational systems.

  5. 2020

    StereoSet and a VentureBeat award

    He wins the VentureBeat AI Innovation Award in NLP/NLU in 2020 for his work on StereoSet, a dataset that measures stereotype bias in language models.

  6. 2021

    MaRVL and cross-cultural reasoning

    He coauthors MaRVL, a multilingual visual-reasoning dataset built from native-speaker annotations in Indonesian, Mandarin, Swahili, Tamil, and Turkish. The paper wins the Best Long Paper award at EMNLP in 2021.

  7. 2023–2024

    StarCoder and LLM2Vec

    In 2023, he coauthors StarCoder, a code model from the BigCode open-science collaboration; StarCoderBase is trained on one trillion tokens from The Stack. In 2024, he coauthors LLM2Vec, an unsupervised method that transforms decoder-only language models into text encoders.

  8. 2025

    A CS-CAN early-career award

    He receives the CS-CAN Outstanding Early Career Computer Science Researcher Award in 2025.

  9. 2026

    An Alfred P. Sloan Fellowship

    He receives the Alfred P. Sloan Research Fellowship in 2026.

  10. As of October 2026

    Mistral and McGill roles

    As of October 2026, he is an AI Scientist at Mistral and its first researcher in Montreal. He is an Associate Professor in McGill's School of Computer Science and Department of Linguistics, currently on leave, and a Canada CIFAR AI Chair; he also co-leads the McGill NLP Group. He is a core academic member of Mila.
