Dr. Matt Orr studies the intersection between behaviour, education, health, and technology. His research projects have primarily examined the use of novel technology to modify or measure the behaviour of children and youths in home and school settings, but have also examined sleep and dreams, social media, and role-playing games. The research methods he most employs involve mobile sensing, digital phenotyping, ecological momentary assessments, online surveys, and qualitative interviews. When developing new technologies, he primarily uses Flutter and Dart.
