First, you gotta go read the piece: UCSC Engineering Building Attacked by Giant Gorilla.
Now that you’ve read it, to answer your questions:
• Yes, that’s Sean’s college.
• Yes, that’s Sean’s department.
• No, to the best of our knowledge, he didn’t work on it.
• No, we didn’t ask him about it when he told us about the stunt, because he didn’t tell us about the stunt—I heard about it from Brad.
Or in short: we think that it’s very kewl, and we wish he’d worked on it. [And kid: call home, your mom wants to hear from you occasionally.]
