Howdy! Welcome to Junnan Yu's Homepage!

Junnan Yu is a Ph.D. student in Information Science at the University of Colorado Boulder, Colorado, United States. He is a member of the Creative Communities research group. Advised by Professor Ricarose Roque, his research is focused on STEM education and interactive learning technologies for children. Currently, he is exploring (1) how to bring Computer Science education to the playground for young children through physical activities and (2) the understanding and supporting of young children's learning with coding toys and kits.
