I'm looking at applying to do a fully funded PhD but I graduated 12 years ago. I know friends who went straight from uni to post-grad stuff and they were all heavily guided on the subject of research themes when doing their applications or were applying for a very specific project.
I've been working in a related field for the past 5 years but I'm wondering how best to decide on a research theme from the very little information given, it's a fairly broad area of interest. Does the fact that I can't work out a research theme indicate it's probably not for me?
