Her first book, Addiction by Design: Machine Gambling in Las Vegas (Princeton University Press 2012), draws on extended research among compulsive gamblers and the designers of the slot machines they play to explore the relationship between technology design and the experience of addiction. Her next book, Keeping Track: Sensor Technology, Self-Regulation, and the Data-Driven Life (Farrar, Straus, and Giroux, forthcoming 2017), concerns the rise of digital self-tracking technologies and the new modes of introspection and self-governance they engender.
