[Gravity Falls] Spoiler Question about Stanford Pines. (Spoilers)

So in the chronology of Gravity Falls, Stanford Pines was given a large grant by his University to conduct research in Gravity Falls, Oregon. 

But for at least 30 years, Stanley Pines impersonated Stanford Pines, and converted his research station into a Tourist Trap. 

Was the University not privy to this? Was Stanley sending them falsified research?

He's a skilled conman and liar, very good at fast talking, much smarter then he seems and can impersonate his brother very well.

He probably can't impersonate a scientist to fellow experts, but he can come up with a convincing reasons that he is giving up on his academic projects that only comes off as "tragic wasted potential" rather then "actually a different guy".

Once that happens, the university has no further reason to investigate that student who went nuts and started running a gift shop in some backwards town somewhere.
