Hi! I am a 5th-year PhD student 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 academic interests broadly lie in the learning sciences, cognitive science, human-computer interaction, learning analytics, and Open Educational Resources (OER). During my doctoral study, my research has focused on (co-)designing Intelligent Tutoring Systems and using them as a platform to explore fundamental questions about human learning. 

I work with stakeholders (educators and students) to find 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 the graduation from International Christian University in Tokyo where I received my bachelor’s degree in Education.

Feel free to get in touch! I can be reached at tnagashi[at]cs.cmu.edu.
