Hi! I am a PhD Candidate in the Human-Computer Interaction Institute (HCII) at Carnegie Mellon University, where I am advised by Professor Vincent Aleven. Before joining CMU, I completed my Master’s degree in Learning, Design, and Technology at Stanford Graduate School of Education, working with Professor Candace Thille on Open Learning Initiative at Stanford.

My work lies at the intersection of the learning sciences, cognitive science, and human-computer interaction. I co-design intelligent technologies use them as a platform to explore fundamental questions about human learning. For example, my research has focused on:

  • Designing novel instructional strategies that help learners reason with visual information in an intelligent system
  • Designing an educational game that is engaging and effective
  • Re-conceptualizing classroom research as a mutual, equitable learning opportunity between researchers and practitioners
  • Supporting learners’ autonomous choice making in an intelligent system

I work with stakeholders to find real-world problems, design and evaluate tools, strategies, and digital technologies in a variety of learning environments. I am also actively working in the OER community as a member at Creative Commons Japan and as an OER Research Fellow at Open Education Group.

Prior to coming to the US, I spent two years working at the Center for Open Education at Hokkaido University (Japan) as an instructional designer, following my graduation from International Christian University in Tokyo where I received my bachelor’s degree in Education.

I am on the job market looking for TT faculty and industry positions (UX or learning research role) inside and outside US! Feel free to get in touch – I can be reached at tnagashi[at]cs.cmu.edu.
