Hello! I have a first degree in Psychology but my Master's degree is Information Management. Do I eligible to register for Phd in Computer Systems? May I know how to find supervisors who have any ideas on these areas? Thanks.

Sorry, Norain, I'm not expert in computer area, but maybe you can seek some suggestions from your supervisor when you were doing your master degree.

And i think it is also possible to serf the web-pages in some universities and ask for suggestions from some research tutors in their universities

You are probably eligible for such a course. If you can't find what you're looking for here then try the web sites of university information science/computing departments.

DanB, you missed one!
