I study how people work with AI systems as they increasingly enter domains of professional expertise and authority that have long defined human work and organizational life. This line of research asks: how do workers negotiate responsibility and professional authority as AI takes on core professional capacities, and how can these systems be designed and governed to function as responsible collaborators in the workplace?

I study how people relate to AI systems as they increasingly enter domains of emotion, intimacy, and companionship that have long been central to human social relationship. This line of research asks: how do users build and experience relationships with AI, how do value conflicts emerge in emotionally engaging interactions, and how can these systems be designed to support care, safety, and human well-being?

I study how people interact with AI systems as they increasingly take on cognitive capacities that have long been central to human thought, including information seeking, reasoning, and decision-making. This line of research asks: what happens when people delegate core cognitive work to AI agents, where do breakdowns and risks emerge, and how can these systems be designed to support effective, accountable, and secure human-agent collaboration?
