I've been offered a PhD at Stirling University in the Biological Sciences department - does anyone know whether this is a well regarded university for Biological Sciences??? I can't find much about it at all on the web...
Best place to find out about research quality is the RAE website which grades universities on research output. You might also take a look at the good university guides from papers such as the Sunday Times which although aimed at undergrads do give a feel for the student experience.
I did my undergrad at Striling (Economics) over 20 years ago - it is a lovely campus but it is a small town which does not suit everyone.
