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?
