Imagine you're a PhD student, and you found a research group, in another university, that you'd like to join for a PostDoc period.
You want to join that group because you really like their subjects, and their projects, and/or for other reasons. You just dediced you would like to join them.
Now, what could you do during your PhD to augment the probabilities to reach this objective?
You might say: just relax, make an awesome work, and then, when you're ending your doctoral period, contact that group PI and ask to be hired (we already discussed how to cope with this phase).
Okay, but, is there something you could do during your PhD before that moment?
What could you do?
Keep up-to-date on their scientific papers?
Email them? About what? Visit their lab?
Thanks a lot
