I build artificial intelligence (AI) frameworks that apply data science approaches in human computer interaction (HCI) settings to train, coach, and assist humans. I use data science to model “mastery” within human performances of complex skilled activities, e.g. surgery. Such intelligent systems can assist humans in two roles: 1) a co-teacher, i.e., an active guide for a human learner who is beginning to develop the skill, and 2) a co-expert, i.e., an active assist for a human performer who has demonstrated competency in executing the skill.

My research program focuses on AI-augmented learning side of HCI, which is building and studying intelligent machines that teach humans to master specific skills while improving outcomes of such skilled tasks.
