Education and Early Career
Margaret Mitchell studied linguistics at Reed College. She earned her bachelor's degree in 2005. Linguistics is the study of language.
After college, she worked as a research assistant. Then, she got her Master's degree. This was in Computational Linguistics from the University of Washington in 2009. Computational linguistics combines computer science and language.
She then went on to earn her PhD. She studied at the University of Aberdeen. Her doctoral thesis was about how computers can describe things they see. She finished her PhD in 2013.
Career in AI Research
Mitchell is well known for her work on making AI fair. She also helps fix algorithmic bias. This means she works to stop computer programs from being unfair.
Making AI Fair
She helped create 'Model Cards'. These are like nutrition labels for AI models. They explain what the model does and how it should be used. This makes AI more transparent.
She also developed ways to remove biases from AI. This helps make sure AI treats all groups of people fairly. Her methods test AI to find and fix unfairness.
Working at Microsoft and Google
In 2012, Mitchell joined Johns Hopkins University. She worked there as a researcher. The next year, she moved to Microsoft Research.
At Microsoft, she led the Seeing AI project. This is a special app. It helps people who are visually impaired. The app can describe texts and images to them.
In 2016, she became a senior research scientist at Google. There, she helped start a team. It was called the Ethical Artificial Intelligence team. She led this team with Timnit Gebru.
In 2018, she spoke at a TED talk. Her talk was about building AI to help humans. She explained how AI should be helpful, not harmful.
Advocacy and New Ventures
Margaret Mitchell has always spoken up for diversity. She believes in having many different kinds of people in tech. She also raised concerns about research freedom at Google.
In 2021, she left Google. Later that year, she joined Hugging Face. This is an AI start-up company.
Leadership and Community
Mitchell helped start a group called Widening NLP. NLP stands for natural language processing. This group works to get more women and minorities involved in the field. It is part of the Association for Computational Linguistics.
