My research is in human-computer interaction, with a focus on next-generation interaction techniques, such as brain-computer interfaces, physiological computing, and reality-based interaction. I design, build and evaluate interactive computing systems that use machine learning approaches to adapt and support the user’s changing cognitive state and context. I also investigate effective human interaction with complex and autonomous systems and vehicles. My work has applications in areas such as education, transportation, medicine, creativity support, gaming, and complex decision making.
