I am an Assistant Professor in the School of Information Sciences (iSchool) at the University of Illinois Urbana-Champaign, with a joint appointment in the Department of Educational Psychology. I am also a faculty affiliate at the National Center for Supercomputing Applications (NCSA), and a faculty affiliate in Illinois Informatics.
My research employs machine learning to model emotion, engagement, and learning, with a special focus on the fair treatment of students who are members of underrepresented groups.
I work with data from various sources such as facial expressions, clickstream logs, and eye gaze tracking. In conjunction with many excellent collaborators here at the University of Illinois and elsewhere, my research focuses on topics including:
- Human-computer interaction in educational software (e.g., how can we improve educational software via models of emotion?)
- Online education (e.g., do students' online interactions with each other reveal aspects of their learning processes?)
- Egalitarian data mining (e.g., how can we reduce imbalances in accuracy for machine learning models across demographics?)
- Interpretable knowledge discovery from human behavior data (e.g., can we discover predictive, dynamic facial expressions via neural networks?)
