I obtained my PhD from a very low ranked university in Africa. Research was really hard due to a lack of many resources. But by working hard I managed to land a postdoc at a top world research intensive university. It wasn't easy to get the job as I had good papers but published in "average" journals. My PI even told me that I need to publish in top quality journals because that was the main issue in my profile and other candidate.
6 months later, my previous PHD supervisor wants me to do research with him. There were a couple of research papers that I was working on with a PhD student in my previous lab, my ex-supervisor also had an idea for another paper. I don't how to approach this situation because I have the following issues:
- I need to publish in top quality journals and I don't think I would be able to do so if I helped my previous team. To be honest, the "average" journals I published in were the best ones my previous teams published in.
- I also need to publish!
- I don't know how my PI will take this. Perhaps I need to use my old affiliation!
- This will probably steal a few weekends from me. I am not planning to dedicate a lot of time to my previous team.
Sometimes it looks that doing research with my old team has more harm than good for my profile. Sometimes, I say "why? it's just research". Should I do research with my previous team? What advice would you give me?
