I am an educational technologist focusing on ways to make learning experiences more engaging, efficacious, and enjoyable. Access to computers at school has greatly increased worldwide and across socioeconomic groups in recent years. The potential of educational software lies in its human-like ability to provide personalized just-in-time guidance, combined with greater ease of deployment and inherent flexibility. My research informs the design of next-generation educational technologies, supporting both social and cognitive aspects of learning. My interests encompass several threads: engendering rapport and relationships with social technologies to aid learning, cultural issues in educational technologies, and supporting cross-discipline development of educational games. Individual projects typically cut across several threads, and include the development of new technologies as well as contributions to learning theory.
