I'm in cardiovascular sciences - but I did my undergrad here too, in neuroscience
That's true though - it doesn't do an awful lot in things like neuropharmacology. It's more cardiovascular and ion channels type stuff, as well as neurodegeneration.
As for the student areas being crime-ridden... It has a bit of a bad reputation, really (probably due to silly students forgetting to lock their doors....). I've certainly never had any problems. Saying that, I haven't lived in Hyde Park or Woodhouse (look at a map if you're interested!) which are probably the worst ones, Woodhouse seeming worse than Hyde Park. Headingley is fine - I've lived there and so have loads of other people I know. Same goes for Burley Park - never had any problems.
I've moved a bit further out for the last 1 and a half years, to Horsforth. It's not a student area as such. but I'm sure it's got some affordable places. It's really nice too
Anyway, I have work to do...
