According to his CV, he did get tenure.

At Georgia Tech, not at MIT. Still a great achievement though (go Jackets!).

Edit: my bad, looks like he was an associate prof at MIT, which means he was indeed tenured before moving to Tech!

I have no idea what happened in this case, but that doesn't follow - MIT is one of those schools that routinely promote to associate without necessarily giving tenure [0].

Interesting, thanks!

There is a position at MIT called associate prof without tenure. So just because he was an associate prof doesn't necessarily mean he had tenure.
