Potential PhD students
-
My group is looking for PhD students to work with us. You need to have strong technical skills, and be motivated to build novel interactive technologies that better understand and better respond to humans. Please have a look at my research and publications pages to get an understanding of the research we do. If you send me an email regarding doing a PhD, please include your CV and a summary of the kind of research you want to do.
