Jeffery Dean: Google AI

Here is the wiki article. 

Here is the article about AI scientist and her resignation. 

The projects Dean has worked on include:

• Spanner, a scalable, multi-version, globally distributed, and synchronously replicated database
• Some of the production system design and statistical machine translation system for Google Translate
• BigTable, a large-scale semi-structured storage system^[3]
• MapReduce, a system for large-scale data processing applications^[3]
• LevelDB, an open-source on-disk key-value store
• DistBelief, a proprietary machine-learning system for deep neural networks that was eventually refactored into TensorFlow
• TensorFlow, an open-source machine-learning software library^[3]

He was an early member of Google Brain,^[3] a team that studies large-scale artificial neural networks, and he has headed Artificial Intelligence efforts since they were split from Google Search.^[10]

Dean was the subject of controversy when ethics in AI researcher Timnit Gebru challenged Google's research review process, ultimately leading to her departure from the company. Dean responded by publishing a letter on Google's approach to the research process^[11] that was the subject of further criticism and controversy.^[12]
