Timeline

  1. October 2017–November 2022

    Robust meta-learning at Amazon

    She works as a Research Scientist at Amazon Web Services from October 2017 to November 2022. In 2021, she coauthors a method that selects informative examples to make few-shot meta-learning more robust.

  2. 2020

    Bayesian methods for privacy

    In 2020, she completes a computer-science doctorate at Boğaziçi University. Her dissertation explores privacy-preserving data sharing through Bayesian inference, differential privacy, and coupled tensor factorization. She also holds a Master of Science in Computer Science from Boğaziçi and a Bachelor of Science in Computer Engineering from Bilkent.

  3. 2024

    LLM evaluation and Aya Expanse

    In 2024, she coauthors Elo Uncovered, which finds that Elo computations can be volatile and that reliability and transitivity can fail in language-model evaluation. In December 2024, she coauthors Aya Expanse, an 8B and 32B multilingual language-model family.

  4. July 2025

    Multilingual arbitration

    At ACL in July 2025, she coauthors Multilingual Arbitration, a method that routes samples through several models based on each model's strengths for individual languages to improve multilingual performance.

  5. Since January 2023

    Senior Research Scientist at Cohere

    She joins Cohere as a Senior Research Scientist in January 2023. At the Cohere Labs Connect Conference in 2025, she speaks as a Research Scientist at Cohere Labs. In 2026, she coauthors Tiny Aya, a small multilingual model family trained on 70 languages.
