Has anyone been a non-student staff member of a research lab at a (reputable, US) university starting from an entry/Bachelor's degree-level position, then leveraged their years of employment as the basis for a dissertation to receive an advanced degree from the same university with some minimal additional coursework/research/etc.?
Would this route be frowned upon at all, or have some other downsides I've yet to consider? If such an option exists, is there a name or label usually used to describe this? Is this more plausible for a Master's (rather than a PhD)?
To clarify, I am not asking about honorary doctorates. I'm satisfied with my contributions over the past ~4 years, but nonetheless I haven't made exceptional contributions to qualify for such a thing, nor am I interested in getting an empty title from some disreputable source.
I am trying to understand if this is something that is actually plausible and worth looking into or not.
