I am currently a Researcher at the German Research Center for Artificial Intelligence (DFKI). I am also a Faculty Associate at the Berkman Klein Center for Internet & Society at Harvard University

I am a learning scientist, HCI researcher, and open education advocate who works with education stakeholders to support meaningful human learning activities with technologies. I co-design intelligent technologies with educators and learners, and conduct school-based experimental studies to understand and support human learning. My research has explored topics such as:

  • Co-designing novel interaction strategies with teachers to help children reason with, and learn from, visual representations in an intelligent system
  • Supporting learners’ self-regulated choice-making behaviors in an intelligent system
  • Designing an educational game to support engaging and effective learning in math

I received my Ph.D. in Human-Computer Interaction from Carnegie Mellon University’s HCI Institute working with Dr. Vincent Aleven. Prior to attending CMU, I completed my Master’s degree in Learning, Design, and Technology at Stanford Graduate School of Education, working with Dr. Candace Thille.

I am also an activist working in the area of open education as a member of Creative Commons Japan and as an OER Research Fellow at Open Education Group.
