Hello! I use data to understand, model, predict and improve human learning. I deliver data-driven, actionable insights in various educational technologies. While pursuing a Ph.D. degree at NC State, I authored several journal and conference publications, including best student paper nominees at the International Conferences on Artificial Intelligence in Education, and Educational Data Mining. I am the winner of NC State Computer Science Department's Outstanding Research Award in 2018.
