There’s widespread popular concern about AI and the mysterious algorithms behind some of the world’s most valuable products.

I believe this concern is due, in large part, to a lack of awareness about this technology: how it works, how it’s used, and the processes that surround it. While work in this field can be very technical, the basic principles behind it are simple. I’m here to make an understanding of this technology more accessible and to discuss its implications based on this shared understanding.

I’ve been building or leading teams that build artificial intelligence systems for the past fifteen years. This has included time on News Feed at Facebook and in Windows and Office at Microsoft, as well as time in the startup world, most recently leading Grammarly’s applied research, machine learning, and computational linguistics teams across North America.

Currently, I’m leading the knowledge graph team at Twitter.
