Why are disagreements so much more likely to escalate online than in person? How might social media and messaging apps encourage more constructive interactions? Do we pick up new conversational habits from Siri and Alexa? The way we communicate with one another has important consequences for our relationships, and designers play a role in shaping these interactions. My lab investigates the design of systems that encourage constructive conversation.

What common design approaches undermine users' intentions or make their lives worse? My lab investigates how interfaces manipulate users' decisions and attention. We also design alternative patterns to support users in engaging with technology in ways that are consistent with their values and goals.

Have you ever looked up from your phone only to wonder where the last thirty minutes went? My past work documents the "30-minute ick factor" that many people feel after spending time online. My lab studies this experience, builds interfaces that encourage more intentional usage habits, and invents design methods to help practitioners create experiences that are more supportive of users' needs and autonomy.

Ethical design is particularly important in interfaces for children, who are often uniquely vulnerable to exploitation by interfaces. My lab designs experiences that are sensitive to children's developmental needs and platforms that prioritize high-quality content.

How "conversational" should a conversational agent be? Should personified interfaces have designed personalities? When do these human-like systems become creepy? My lab investigates the ways in which personified interfaces support their users, particularly children and families, and common pitfalls in creating these systems.
