Uh-oh...I had the misfortune of running across
my university stalker yet again... He was staring at me non-stop. Fortunately, my friend was sitting next to me; and whenever we talked together, we could, from the corner of our eyes, see him continuing his staring session. My friend proceeded to give me a crash course in confident body language and "get-away-from-me" strategies in a series of whispers; and in the meantime, I could feel that stare drilling into the back of my neck.
Definitely a creep. Have you tried talking to him? He might have a perfectly good reason for it...
Errr, no, don't talk to him. See if you can surreptitiously get a picture of him and report him to campus police. Is he even a student? I'm sure the police would like to have a conversation with him. maybe scare him straight. A Guy
I pretend like I can't see him at all and ignore him completely - I think it's better not to give him any attention, because his staring indicates that he wants my attention, so he's not going to get it. I'd only be able to report him if he resorted to actually threatening me verbally or physically. Until then, I don't think I can report him for staring and following me at a distance on one occasion; there's not enough hard evidence. Taking a picture surreptitiously would be really difficult, considering his constant staring, and I'm not sure whether it is legally allowed

He certainly seems to be a student - he can log into the uni computers, and you need a student ID for that.
Another thing I'm paying attention to is my body language (make yourself straight and tall, hold your head high, avoid a submissive or distracted stance) and being aware of my surroundings (fortunately I know the building and surroundings very well - I was able to throw him off my track the time he followed me).
If he does try to get too close/invade my personal space, then I'll have no qualms about confronting him verbally (and in a very loud voice).
