Researcher

Margaret Mitchell

Margaret Mitchell is a researcher whose work connects language technology with responsible AI practice. Her training includes linguistics at Reed, computational linguistics at Washington and a computer-science doctorate. She worked on image descriptions at Microsoft Research and founded and co-led Google’s Ethical AI team. With colleagues, she proposed model cards: short records of a model’s intended use, testing and performance limits. She also contributed to research on internal algorithmic audits and the ethical risks of evaluating facial systems. Mitchell later joined Hugging Face, where she worked on data governance and documentation tools. She is a researcher and Chief Ethics Scientist at the Ada Lovelace Institute. Her work gives developers and the public concrete information for examining AI systems.
