The School of Computer Science has a number of fully-funded PhD scholarships available.
I'd be interested in hearing from anyone interested in working on complex systems, complex networks, sensor networks, or situation recognition. You can find more details about what I'm interested in here. I'm particularly interested in people wanting to cross disciplines somewhat, into applications in environmental science, medicine, or the digital humanities.
The full advertisement is here. Deadline for applications 31 March 2015.
