I'm a medical student planning on taking a year off in the middle to do research. I'm currently at the same intitution as when I was an undergrad (~4 yrs ago) and want to do research in roughly the same area. I did a decent amount of research as an undergrad, all in a single lab. The research area I'm interested in is pretty small and everyone knows each other, regularly does joint journal clubs, etc.
Question: Does it matter if I reach out to the same lab I used to work in? Would it be weird if I did? Would it be rude/inappropriate if I didn't? If I do reach out to a different lab, would it be expected that I ping my old adviser to say I'm back working in research, anyway (so I don't surprise them when I run into them randomly)? Or does none of this matter very much?
I guess I'm just ignorant about the etiquette surrounding stuff like this and was hoping for some clarification. To be clear, I had no problems with my previous lab--I had a good experience and liked my old adviser.
