My research concerns human-centred design of new technologies for learning. It involves gaining a deep understanding of how people work, play, learn and interact as a foundation for the design of novel socio-technical systems (people in interaction with technology). I am Academic Lead at Futurelearn, and co-investigator on the Wolfson OpenScience Laboratory and Juxtalearn projects. Previous projects as Principal Investigator include Personal Inquiry to support inquiry-based learning of science topics between formal and non-formal settings, and a collaboration with Sharp Labs Europe to develop software on mobile phones for incidental language learning. I was Founding President of the International Association for Mobile Learning. Iam an Associate Editor of IEEE Transactions on Learning Technology, and am a member of the Editorial Board of the Journal of the Learning Sciences and the Journal of Computer Assisted Learning. I have authored 200 papers in the areas of educational technology, human-centred design of personal technologies, learning sciences and cognitive science.
