Voice interfaces like Siri and Amazon Echo have become pervasive. We are exploring what worries people about these interfaces, what they love, and how they use them.

Would you know if your device was listening to your conversations? How do you feel when an app tracks your location? We are studying people's security choices and when and why they trust technology.

Can devices teach self-regulation, rather than trying to regulate children? We are examining how the design of a technology makes it easier or harder for kids to put down when it's time to stop.

Have you ever found yourself embroiled in an argument on social media? We are studying the ways in which the design of a platform changes the tenor of a conversation and what leads to friendship, fights, and reconciliation.
