Researcher

Jilin Chen

As of October 2026, Jilin Chen is a researcher at Google Research whose work spans fairness, calibration and AI safety. Earlier papers from 2021 and 2022 covered fairness-accuracy trade-offs in multi-task learning and a human-ML framework for video content reviews. In September 2023, Batch Calibration, a paper on calibration for in-context learning, appeared on arXiv with Chen as a co-author. Chen is listed as Lead for Safety in the Gemini 1.0 contributions, and later work includes contributions to the Gemini 1.5 report in March 2024 and the Gemini 2.5 report in July 2025. He also co-authored Holistic Safety and Responsibility Evaluations of Advanced AI Models, which appeared on arXiv in April 2024.
