@Knowsstuff – yes, I’ve suggested industrial engineering but so far no interest. I think it’s because he perceives it as too manufacturing oriented which is not his thing so far. But it’s one of those things where with more exposure he might change his mind…
The consistent thing I’ve heard from him is interest in tech industry and product design / development. He talks about being on the business side of the house eventually but wants the knowledge (and credibility) of having an engineering background as his foundation.
If you were to meet him you’d think business / deal making – he’s very charming and socially at ease with all types of people. He flows across several friend groups.
I also happen to think he’d also be a great lawyer b/c he’s tenacious in an argument and good at getting what he wants! 
He’s more been talking about an MBA at some point after undergrad but is intrigued by the IBE model too…
