Can you please stop saying "at Singularity Institute", "within Singularity Institute", et cetera? As has been explained before, this is annoying, grating, and just plain goofy. It makes you sound like a fly-by-night commercial outfit run by people who don't quite speak English.

Actually, I think this is a linguistic corner case in whether you ought to use the word "the", and some speakers/dialects will fall on either side. Consider:

She works at the institute.
* She works at institute.
She works at SingInst.
* She works at the SingInst.
? She works at the Singularity Institute
? She works at Singularity Institute
(* denotes a sentence that is incorrect to all speakers and ? denotes a sentence that is incorrect to some speakers but not all.)

If Singularity Institute parses as a modified noun, then it should have an article. If it parses as a name, then it shouldn't. You can force it to be a name by either compressing it into something that isn't a regular word (SingInst), or by adding something that's incompatible with regular words. Compare:

He will attend the Singularity Summit.
? He will attend Singularity Summit.
He will attend Singularity Summit 2012.
* He will attend the Singularity Summit 2012.

And that's the entire fact of the matter. From a linguistics perspective, whether a sentence is grammatically correct or incorrect depends solely on the intuition of native speakers; and if native speakers disagree, then it must be a dialect difference. Arguing what is "correct" in a speaker-independent sense is meaningless and unproductive.
