I am an Assistant Professor (Research) at the Graduate School of Education and Computer Science (by courtesy) at Stanford University. I am also the Ram and Vijay Shriram Faculty Fellow at the Institute for Human-Centered AI (HAI) and a core faculty member of Stanford HCI. My research asks how we design AI to extend human thinking rather than replace it. I take a cognitively grounded approach to HCI, studying how people build knowledge through acts of creation: writing arguments, building models, drawing diagrams. I then design interfaces that make these cognitive structures visible and interactive, so that AI can meaningfully participate in the process without taking it over. This work spans AI thinking tools that preserve learners' roles as active creators, pedagogical systems that help teachers see and support how students learn, and design methods that give educators real agency in shaping the AI tools entering their classrooms.
