I recently contacted a professor whose field of study is something that I really want to work on. He replied, that frankly his lab was pretty full at the moment, but he'd love to hear about my plans for graduate school. Since I have already secured funding, I guess this does not automatically disqualify me from working in his lab. My only concern is that in such a large group of people, and not as a student working off of funds the professor secured, I would not get the kind of mentorship I would get in a smaller lab. Just looking for any insight that could help me in making some choices in the future.

    Take a look at where previous students from that lab have gone once they graduated. This can give you a good idea at how successful the professor's lab is to learning the research trade.

  • Any idea on how to go about getting that information on a particular professor? Just lot of educated googling?

Being part of a big lab has pluses and minuses, and whether it's a good thing for you is likely to depend much on your personality and circumstances.

  • Cons: you've put your finger on the key fact, that students in big labs are likely to receive much less attention that students in small labs. You also might end up as a just small part of some big project, or even just a glorified lab tech.
  • Pros: in order to support so many students, a professor generally needs to have good funding and being doing research that lots of people find exciting. This means that the projects you are working on are likely to have people paying attention to them, and that if you do well, you may have a powerful backer.

For somebody who thrives in a big, competitive environment, a big lab may be good. For somebody who wants a more personal relationship with one-on-one tutorial, a small lab is probably better. All sorts of labs and advisors can be routes to good careers, however, and it's a matter of figuring out what works best for you.


most important questions on my opinions are:

  • average time to get the diploma in that lab? You might not realize it, but as you get into grad school, you are slave labor: you are at the mercy of the prof who decides when you graduate. If you're really good, s/he might want to keep you around for a while... don't be over zealous!

  • following up on this topic, a small lab may mean longer time too: if the prof has a hard time getting students, you might get a lot more attention than you wanted!

in short, i think a big lab is not a bad thing: whatever you end up doing, if the lab does hot research, you were part of it, even if you spent most of you time doing petty tasks, and in the eye of employers, that's all that matters. Nobody is going to call your prof to ask what you achieved: if he's such a hot shot he won't pick up the phone anyways.

  • @TobiasKildetoft, just curious but why? This isn't the first time I've heard the analogy.

  • @gwg Why would that make it any more ok? May 26, 2016 at 18:28
  • @TobiasKildetoft, let me rephrase: why do you think the analogy is incorrect?

    @gwg Then I don't see how you can ask the question. Graduate students are paid and are free to leave at any time. May 26, 2016 at 18:40
