Big Lab vs Small Lab for Postdoc? I need a point of view of users here regarding doing postdoc in small lab or big lab. I am currently looking for a postdoc position. During my PhD years, I worked in a small lab with inexperienced supervisor as principal investigator. She was a very nice supervisor who is concerned a lot regarding my PhD study. However, she has a weakness of not publishing a lot papers into journal and she is also not a risk taker when it comes to researching high impact research that will result in novel and interesting findings. As a result, I did not manage to publish a lot during PhD study but somehow I did manage to have a smooth PhD study without too many problems because my previous supervisor helped a lot. 

Now, I am researching/ looking for a lab to do postdoc study. While I already received an offer from my previous PhD supervisor to do postdoc with her, I am contemplating to accept that offer due to the fact I mentioned before that her lab is small and she doesn't focus much on publication. I want to keep my options open to the big lab that might have more experts in my field and more publication opportunity. On the other hand, my previous supervisor is a very nice supervisor who is a great leader and boss. And the grass is not always greener at the other side so who knows I might not like new lab.

So the question is, big lab or small lab is better for postdoc research?

There is not inherently an answer to this question, but rather plusses and minuses. For example:

Big Labs:


Lots of people around mean it's likely easier not to feel isolated
May have more secure funding
Presumably put out more papers
Professors are more likely to be dealing with keeping that lab funded, so if you were hoping to learn directly from them, this might not be as easy
It's also easy to get lost in a big group and be incorporated into "Professor So-and-So's Group" without establishing an identity


Small Labs:


A larger % of the lab's productivity rests on each person, so there may be more pressure
Might be dependent on a single grant
Likely more personal attention from the PI
More likely to end up as the first author on most of your papers


My suggestion, having been part of labs of all sizes at various stages of my career is to get experience with both, so that you can find what style works best for you and try to pick and choose what you liked from both.
