Conversational Human–AI Interactions Lab
At Northeastern University, we explore how conversational AI can personalize, collaborate, and support—while respecting human agency.

What we’re here to learn
Our research framework
From understanding an experience to creating and refining it. Each question informs the next.
How do people experience AI?
We study how people perceive, trust, and build relationships with conversational systems. Understanding those experiences is the starting point for thoughtful design.
What could a better conversation look like?
We bring design, HCI, and AI together to create voice assistants, chatbots, and interactive agents that respond to real human needs.
How do we make it work better for people?
We evaluate and improve conversational experiences, asking what makes an interaction useful, responsible, and respectful of human agency.
