<p>What does your question have to do with the study? The study only applies to holders of a baccalaureate, not an advanced degree.</p>
<p>As far as doing research after your PhD, it has a lot more to do with who your advisor was and what your research topic was than it does what school you went to. The biggest advantage of going to a prestigious school is that they have a larger number of big, visible research projects and faculty, so you are more likely to be in one of those good situations. Personally, I am working on my PhD at Texas A&M and my advisor is an NAE fellow and was an editor for several journals in my area and the project I am on is sponsored by NASA Langley, so I really doubt I would have a hard time getting a job at a decent research school or at NASA as long as my grades and other stats are fine when I am finished. I feel like the biggest thing about a place like MIT is that everyone is in on projects/groups like that, not just some or most.</p>
